It is narrated from Sayyiduna Uqbah bin Amir (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: On the Day of Resurrection, the first two disputants will be two neighbors.

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Seek refuge with Allah from the evil of the neighbor in your permanent residence, for if a person is a traveler, he can separate from (the bad neighbor) whenever he wishes.

It is also narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: By Allah! That man cannot be a believer, by Allah! That man cannot possess faith, by Allah! That person cannot be a true believer. The people asked: O Messenger of Allah! Who is he? He, peace and blessings be upon him, said: The neighbor whose neighbors are not safe from his evils. The people asked: O Messenger of Allah! What is meant by "bawa'iq"? He, peace and blessings be upon him, said: His evil.

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him and his family) said: By Him in Whose hand is my soul! That servant will not enter Paradise whose neighbors are not safe from his evil.

Hazrat Abdullah (may Allah be pleased with him) narrates that a man said: O Messenger of Allah! When I do a good deed and when I do a bad deed, how will I know that I have done good or bad? The Prophet (peace and blessings be upon him) said: When you hear your neighbors saying that you have done good, then you have done good; and when you hear them saying that you have done bad, then you have done bad.

It is narrated from a man named Daisam of Banu Sadoos, he says: We said to Sayyiduna Basheer bin Khasasiyyah—this was not his name, the Prophet (peace and blessings be upon him) named him Basheer—anyway, we said: Some people of Banu Tameem are our neighbors, whenever any of our goats strays from the herd, they take it away, so when some of their belongings come to us, can we take possession of them? He said: No, you cannot.

It is narrated from ‘Ubada bin Nusi, who says that Sayyiduna Shaddad bin Aws (may Allah be pleased with him) began to weep. Someone asked him: Why are you weeping? He said: I remembered a hadith that I heard the Messenger of Allah (peace and blessings be upon him) narrate, and that made me weep. I heard him (peace and blessings be upon him) say: I fear for my ummah regarding shirk and hidden desires. I said: O Messenger of Allah! Will your ummah commit shirk after you? He (peace and blessings be upon him) said: Yes, beware! They will not worship the sun, the moon, stones, or idols, but they will show off through their deeds, and the hidden desire is that a servant fasts in the morning, then some desire overcomes him and he breaks his fast.

It is narrated from the Companion of the Messenger, Sayyiduna Abi Saeed bin Abu Fadalah Ansari (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: When Allah Almighty gathers the first and the last on that Day, in which there is no doubt, a caller will announce: Whoever among the servants performed deeds for Allah Almighty, but also associated someone else in them, then let him seek his reward from that other than Allah, for Allah Almighty says: I am the most independent of partners from shirk (association).

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Allah Almighty says: I am the best of partners among partners. Whoever performs a deed for Me and then associates someone else with Me in it, I am free from him, and he is for the one whom he associates.

Ibn Ghanm says: When I and Sayyiduna Abu Darda entered the mosque of Jabiyah, we met Sayyiduna Ubadah bin Samit (may Allah be pleased with him). He took my right hand with his left hand and Sayyiduna Abu Darda’s left hand with his right hand and began to walk between us. We began to whisper, and Allah knows best what we were whispering about. Sayyiduna Ubadah bin Samit (may Allah be pleased with him) said: If one or both of you live long, it is possible that you will see a man belonging to the middle class of Muslims, who will recite the Holy Qur’an according to the tongue of Muhammad, the Messenger of Allah (peace and blessings be upon him). Then he will recite it repeatedly and display it, and he will consider its lawful as lawful and its unlawful as unlawful, and he will adhere to its commands, but still he will bring to you as much good as the head of a dead donkey brings (i.e., that man will not bring even the slightest good or virtue). While we were in this state, Sayyiduna Shaddad bin Aws and Sayyiduna Awf bin Malik (may Allah be pleased with them both) came and sat with us. Sayyiduna Shaddad (may Allah be pleased with him) said: O people! What I fear most for you is what I heard from the Messenger of Allah (peace and blessings be upon him). He (peace and blessings be upon him) said: It is hidden desire and shirk (associating partners with Allah). Sayyiduna Ubadah bin Samit and Sayyiduna Abu Darda (may Allah be pleased with them both) said: O Allah, forgive! Did not the Messenger of Allah (peace and blessings be upon him) say that Satan has despaired of being worshipped in the Arabian Peninsula? As for hidden desire, we know that it is the desires of the world, related to women and their desires, but Shaddad! What is this shirk about which you are warning us? Sayyiduna Shaddad (may Allah be pleased with him) said: Well, tell me about this: if a man prays for the sake of another man, or fasts, or gives charity, do you not think that he has committed shirk? They said: Yes, by Allah! Whoever prays to show someone, or fasts, or gives charity, he has committed shirk. Sayyiduna Shaddad (may Allah be pleased with him) said: Then I heard the Messenger of Allah (peace and blessings be upon him) say: Whoever prays showing off, he has committed shirk; whoever fasts showing off, he has committed shirk; whoever gives charity showing off, he has committed shirk. Sayyiduna Awf bin Malik (may Allah be pleased with him) said: Will it not be that those deeds which he did purely for Allah will be considered and accepted, and the deeds of shirk will be left aside? Sayyiduna Shaddad (may Allah be pleased with him) replied: The Messenger of Allah (peace and blessings be upon him) stated that the Messenger of Allah (peace and blessings be upon him) said: Whoever associates anyone with Me, I am the best of partners and associates; whoever associates anything with Me, all his accumulated deeds, whether little or much, will be for the one with whom he associated, and I (Allah) am free from him.
