On the authority of Abu Saeed Al-Khurdari, who said: I heard the messenger of Allah say:

"Whosoever of you sees an evil action, let him change it with his hand; and if he is not able to do so, then with his tongue; and if he is not able to do so, then with his heart; and that is the weakest of faith."

(Muslim)

Allah says in Surah 64, Ayah 9 what can be translated as: The Day that He assembles you (all) for a Day of Assembly,- that will be a Day of mutual loss and gain (among you), and those who believe in Allah and work righteousness,- He will remove from them their ills, and He will admit them to Gardens beneath which Rivers flow, to dwell therein for ever: that will be the Supreme Achievement.

On the authority of Abdullah Ibn Omar May Allah be pleased with him who said Allah's Messenger said: A Muslim is a brother of another Muslim, so he should not oppress him, nor should he hand him over to an oppressor. Whoever fulfilled the needs of his brother, Allah will fulfill his needs; whoever brought his (Muslim) brother out of a discomfort, Allah will bring him out of the discomforts of the Day of Resurrection, and whoever screened a Muslim, Allah will screen him on the Day of Resurrection.

(Bukhari)

Allah says in Surah 49, Ayah 11 what can be translated as O ye who believe! Let not some men among you laugh at others: It may be that the (latter) are better than the (former): Nor let some women laugh at others: It may be that the (latter are better than the (former): Nor defame nor be sarcastic to each other, nor call each other by (offensive) nicknames: Ill-seeming is a name connoting wickedness, (to be used of one) after he has believed: And those who do not desist are (indeed) doing wrong.

On the authority of Ibn Omar, the son of Omar bin Al-Khattab, may Allah be pleased with both, who said : I heared the messenger of Allah say :

"Islam has been built on five [pillars]: testifying that there is no god but Allah and that Muhammed is the messenger of Allah, performing the prayers, paying the zakat, making the pilgrimage to the House, and fasting in Ramadan."

(Bukhari and Muslim)

Allah says in Surah 12,Verse 76 what can be translated as: Never think that you have reached the final stage of knowledge and nobody knows more than yourself. Remember! Above everyone endowed with knowledge is another endowed with more knowledge.

On the authority of Abu Hurairah, who said: the messenger of Allah said:

p Allah the Almighty has said: "Who soever shows enmity to a friend of Mine, I shall be at war with him. My servant does not draw near to Me with anything more loved by Me than the religious duties I have imposed upon him, and My servant continues to draw near to Me with supererogatory works so that I shall love him. When I love him I am his hearing with which he hears, his seeing with which he sees, his hand with which he strikes, and his foot with which he walks. Were he to ask [something] of Me, I would surely give it to him and were he to ask Me for refuge, I would surely grant him it."

(Bukhari)

Allah says in Surah 4, Ayah 74 what can be translated as:

Let those (believers) who sell the life of this world for the Hereafter fight in the cause of Allah., and whosoever fights in the Cause of Allah, and is killed or is victorious, We shall bestow on him a great reward.

On the authority of Abu Hurairah, who said: The messenger of Allah said :
Each person's every joint must perform a charity every day the sun comes up : to act justly between two people is a charity; to help a man with his mount, lifting him onto it or hoistingd up his belongings onto it is a charity: a good word is a charity, every step you take to prayers is a charity and removing a harmful thing from the road is a charity.

(Bukhari & Muslim)

Allah says in Surah 2, Ayah 280,281 what can be translated as: If the debtor is in difficulty, grant him time till it is easy for him to repay. But if you remit it by way of charity, that is best for you if you only knew. And fear the Day when you shall be brought back to Allah. Then shall every soul be paid what it earned, and none shall be dealt with unjustly.

On the authority of Abu Hurrairah (May Allah Be Pleased With Him), who said: The Messenger of Allah (Peace Be Upon Him) said: "Do not envy one another; do not inflate prices one to another; do not hate one another; do not turn away from one another; and do not undercut one another, but be you, O servants of Allah, brothers. A muslim is the brother of a muslim: he neither oppresses him nor does he fail him, he neither lies to him nor does he hold him in contempt. Piety is right here-and he pointed to his breast three times. It is evil enough for a man to hold his brother muslim in contempt. The whole of a muslim for another muslim is inviolable: his blood, his property, and his honor."

(Muslim)

Allah Says In Surah 8: Ayah 30 What can be translated as:
"Remember how the Unbelievers plotted against thee, to keep thee in bonds, or slay thee, or get thee out (of thy home). They plot and plan, and Allah too plans; but the best of planners is Allah."

On the authority of Abu Hurrairah (May Allah Be Pleased With Him) that the Prophet Mohmmamed (Peace Be Upon Him) said: "Whosoever removes a worldly grief from a believer, Allah will remove from him one of the griefs of the Day of Judgment. Whosoever alleviates [the lot of] a needy person, Allah will alleviate [his lot] in this world and the next. Whosoever shields a Muslim, Allah will shield him in this world and the next. Allah will aid a servant [of His] so long as the servant aids his brother. Whosoever follows a path to seek knowledge therein, Allah will make easy for him a path to Paradise. No people gather together in one of the houses of Allah, reciting the Book of Allah and studying it among themselves, without tranquility descending upon them, mercy enveloping them, the angels surrounding them, and Allah making mention of them amongst those who are with Him. Whosoever is slowed down by his actions will not be hastened forward by his lineage."

(Muslim)

Allah says in Surah 6, Ayah 32 what can be translated as:  And the worldly life is not but amusement and diversion but the home of Hereafter is best for those who fear Allah. Will you not then reason?

The Son of Omar (May Allah be Pleased With Him) used to say:
"At evening do not expect [to live till] morning, and at morning do not expect [to live till] evening. Take from your health for your illness and from your life for your death."

(Bukhari)

Allah says in Surah 18: Ayahs 45-46 what can be translated as:
"And set forth to them parable of the life of this world: like water which We send down from the cloud so the herbage of the earth becomes tangled on account of it, then it becomes dry broken into pieces which the winds scatter; and Allah is the holder of power over all things. Wealth and children are an adornment of the life of this world; and the ever-abiding, the good works, are better with your Lord in reward and better in expectation."

On the authority of Abu Hurairah, who said : I heared the messenger of Allah say :

"What I have forbidden to you, avoid; what I have ordered you [to do], do as much of it as you can. It was only their excessive questioning and their disagreeing with their prophets that destroyed those who were before you."

(Bukhari and Muslim)

Allah says in Surah 18:Verse 103-105 what can be translated as:

Say: Shall We inform you of the greatest losers in (their) deeds? (These are) they whose labor is lost in this world’s life and they think that they are well versed in skill of the work of hands. These are they who disbelieve in the communications of their Lord and His meeting, so their deeds become null, and therefore We will not set up a balance for them on the day of resurrection.

On the authority of Omar Ibn Al-Khattab(May Allah Be Pleased With Him ), who said : I heard the messenger of Allah (Peace Be Upon Him) say "Actions are but by intention and every man shall have but that which he intended. Thus he whose migration was for Allah and His messenger, his migration was for Allah and His messenger, and he whose migration was to achieve some worldly benefit or to take some woman in marriage, his migration was for that for which he migrated."

(Bukhari and Muslim)

Allah says in Surah 57:Ayah 20 what can be translated as :
Know that this world’s life is only sport and play and gaiety and boasting among yourselves, and a vying in the multiplication of wealth and children, like the rain, whose causing the vegetation to grow, pleases the husbandmen, then it withers away so that you will see it become yellow, then it becomes dried up and broken down; and in the hereafter is a severe chastisement and (also) forgiveness from Allah and (His) pleasure; and this world’s life is naught but means of deception.
