It is narrated from Sayyiduna Hudhaifah bin Asid (may Allah be pleased with him) that one day the Messenger of Allah (peace and blessings be upon him) came and said: "Offer the funeral prayer for your brother who has passed away in a foreign land." The companions asked: "O Messenger of Allah! Who is he?" He replied: "Sahmah Najashi." Thus, the companions stood up and offered his funeral prayer.

It is narrated from Sayyiduna Imran bin Husain, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: Your brother Najashi has passed away, so come and offer his funeral prayer.

It is narrated from Sayyiduna Jarir bin Abdullah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: Your brother Najashi has passed away, pray for his forgiveness.

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated a similar narration from the Noble Prophet (peace and blessings be upon him).

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that there was a black man or woman who used to sweep the mosque. He/she passed away. When the Noble Prophet (peace and blessings be upon him) did not see him/her, he (peace and blessings be upon him) asked: What happened to the one who used to clean the mosque? Someone said: He/she has passed away. The Prophet (peace and blessings be upon him) said: Why did you not inform me? The companions said: It happened at night. The Prophet (peace and blessings be upon him) said: Guide me to his/her grave. So the Prophet (peace and blessings be upon him) went to the grave and performed the funeral prayer. The narrator of this hadith, Thabit, while narrating this or another hadith, said that the Prophet (peace and blessings be upon him) said: Indeed, these graves are filled with darkness, and because of my prayer, Allah Almighty has illuminated them.

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that there was a black man who used to clean the mosque. He passed away at night and was buried during the night. When the Noble Prophet (peace and blessings be upon him) arrived, he was informed about this. The Prophet (peace and blessings be upon him) said: "Let us go to his grave. These graves are filled with darkness, and Allah Almighty illuminates them for their inhabitants because of my prayer over them." Then the Prophet (peace and blessings be upon him) came to his grave and performed his funeral prayer. An Ansari companion said: "O Messenger of Allah! My brother had passed away and you did not perform his funeral prayer." The Prophet (peace and blessings be upon him) asked: "Where is his grave?" He informed the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) went there with him.

When he (peace and blessings be upon him) was informed that it was the grave of such-and-such woman, he recognized her and then asked: Why did you not inform me about her? The companions said: O Messenger of Allah! You were fasting and resting (taking a siesta), so we did not consider it appropriate to inform you. The Prophet (peace and blessings be upon him) said: (Do not do so,) whenever any one of you passes away and I am present among you, be sure to inform me, because my offering the funeral prayer for any deceased is a mercy for him. Then the Prophet (peace and blessings be upon him) went to her grave, made us stand in rows behind him, and said four takbirs.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) offered the funeral prayer for a person in the grave after he had been buried.
