And those who disbelieved are allies of one another. If you do not do so, there will be fitnah on earth and great corruption. - Quran Al-Anfal(The Spoils of War) 8:73 (islam)
Chapter: The Prohibition Of Striking The Face
This hadith has been transmitted on the authority of Abu Huraira and in the hadith transmitted on the authority of Ibn Hatim Allah's Apostle (ﷺ) is reported to have said:
When any one of you fights with his brother, he should avoid his face for Allah created Adam in His own image. - Hadith Muslim 2612e (islam)
Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man. - Bible Matthew 15:11 (bible)
O you who have believed, if there comes to you a disobedient one with information, investigate, lest you harm a people out of ignorance and become, over what you have done, regretful. - Quran Al-Hujurat(The Rooms) 49:6 (islam)
[23]Indeed, it is We who have sent down to you, [O Muhammad], the Qur'an progressively.
[24]So be patient for the decision of your Lord and do not obey from among them a sinner or ungrateful [disbeliever]. - Quran Al-Insan(Man) 76:23-24 (islam)
O you who have believed, do not enter the houses of the Prophet except when you are permitted for a meal, without awaiting its readiness. But when you are invited, then enter; and when you have eaten, disperse without seeking to remain for conversation. Indeed, that [behavior] was troubling the Prophet, and he is shy of [dismissing] you. But Allah is not shy of the truth. And when you ask [his wives] for something, ask them from behind a partition. That is purer for your hearts and their hearts. And it is not [conceivable or lawful] for you to harm the Messenger of Allah or to marry his wives after him, ever. Indeed, that would be in the sight of Allah an enormity. - Quran Al-Ahzab(The Confederates) 33:53 (islam)
Chapter: What has been said regarding (re)conciliation between the people
Narrated Anas:
It was said to the Prophet (ﷺ) "Would that you see `Abdullah bin Ubai." So, the Prophet (ﷺ) went to him, riding a donkey, and the Muslims accompanied him, walking on salty barren land. When the Prophet (ﷺ) reached `Abdullah bin Ubai, the latter said, "Keep away from me! By Allah, the bad smell of your donkey has harmed me." On that an Ansari man said (to `Abdullah), "By Allah! The smell of the donkey of Allah's Messenger (ﷺ) is better than your smell." On that a man from `Abdullah's tribe got angry for `Abdullah's sake, and the two men abused each other which caused the friends of the two men to get angry, and the two groups started fighting with sticks, shoes and hands. We were informed that the following Divine Verse was revealed (in this concern):-- "And if two groups of Believers fall to fighting then, make peace between them." (49.9) - Hadith Al Bukhari 2691 (islam)
