It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "The best of companions in the sight of Allah is the one who is best to his companion, and the best of neighbours in the sight of Allah is the one who is best to his neighbour." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

It is narrated from Sayyiduna Abu Shurayh al-Ka'bi (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever believes in Allah and the Last Day, let him honour his guest. His (special) hospitality is a day and a night, and hospitality is three days; whatever is beyond that is charity. And it is not lawful for him (the guest) to stay (with the host for so long) that he puts him in difficulty." In the narration of Ibn Wahb there is this addition: "And his special hospitality is that he honours him on the first day with the best of what he can find." And he said: "Yathwi" means to stay. This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it. Yet its narration from Sayyiduna Abu Hurayrah (may Allah be pleased with him) is also authentic, and I think that they recorded it; but in my view the two Shaykhs left out the hadith of Abu Shurayh because of the narration of Sayyiduna Abu Hurayrah.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever believes in Allah and the Last Day, let him honour his neighbour." And then he mentioned the complete hadith. Imam al-Hakim (may Allah have mercy on him) says: I heard Ali bin Isa saying that he heard Abu Bakr Muhammad bin Ishaq saying: Malik bin Anas, in the matter of this chain, has a stronger memory than a number of people like Abd al-Rahman bin Ishaq; and Abd al-Hamid bin Ja'far has corroborated Malik bin Anas in this narration.

It is narrated from Sayyiduna Abu Shurayh (may Allah be pleased with him) that he said: When the Messenger of Allah (peace and blessings be upon him) spoke these words, my ears heard them, my eyes saw, and my heart preserved them. Then he mentioned the complete narration just like the hadith of Imam Malik. As for the two Shaykhs, they did not use Abd al-Rahman bin Ishaq as evidence.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "By Allah, he is not a believer! By Allah, he is not a believer! By Allah, he is not a believer!" The Companions said: "O Messenger of Allah! Who is that?" He (peace and blessings be upon him) said: "The neighbour whose neighbour is not safe from his bawa'iq." They said: "O Messenger of Allah! What is meant by bawa'iq?" He (peace and blessings be upon him) said: "His evil (wickedness and harm)." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it with this wording.
