It is narrated from Sayyiduna Abu Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "A Muslim has four rights over a Muslim: that he accept when he invites him, visit him when he is ill, respond to him when he sneezes (and praises Allah), and accompany his funeral when he dies." 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 Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Indeed, Allah Almighty loves sneezing, so when one of you sneezes, it is a right upon everyone who hears him that he say 'Yarhamuk Allah' (May Allah have mercy on you)." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it. And Imam Bukhari did not leave out any of these hadiths from his chapter headings (tarajim).

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: "Sneezing is from Allah and yawning is from Satan, and it is a right upon the one who hears (the sneeze) that he say 'Yarhamukumullah' (May Allah have mercy on you)."

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) forbade people from sitting along the sides of the roads. The Companions said: O Messenger of Allah (peace and blessings be upon him), we cannot avoid this (we have need of it). He (peace and blessings be upon him) said: "If not (if you cannot avoid it), then give the road its right." They asked: O Messenger of Allah (peace and blessings be upon him), what is the right of the road? He (peace and blessings be upon him) said: "Returning the greeting, responding to the sneezer when he praises Allah, lowering the gaze, and guiding the one who has lost his way." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
