Hazrat Ali (may Allah be pleased with him) narrates that when Abu Talib passed away, I went to the service of the Noble Prophet (peace and blessings be upon him) and said, "O Messenger of Allah! Your misguided uncle has died." The Prophet (peace and blessings be upon him) said, "Go and cover him, and do not do anything until you come to me." I went and covered him, then returned, and there were signs of dust and dirt upon me. The Prophet (peace and blessings be upon him) gave me some supplications which were more pleasing to me than acquiring the things of this world.

It is narrated in the same way from Hazrat Ali (may Allah be pleased with him, may Allah honor his face), and he states that I was commanded to perform ghusl (ritual bath).

Hazrat Sha'bi narrates that Umm al-Harith bint Abi Rabi'ah, who was a Christian woman, passed away, so the companions of the Holy Prophet (peace and blessings be upon him) attended her funeral.

The same is narrated from Hazrat Aamir.

Hazrat Abu Wa'il says: My mother passed away, who was a Christian. I went to Hazrat Umar and informed him. He said: Mount your ride and walk silently in front of it.

Hazrat Ata bin As-Saib narrates that a man from Thaqif’s mother passed away, and she was a Christian. He asked Hazrat Ibn Ma’qil about this matter. He replied:“I personally prefer to be present at her funeral, but not to walk behind her bier. Then he said: Mount your ride and walk three to four hundred yards ahead of it, because when you walk ahead of it, you will not be counted as accompanying it.”

Hazrat Abdullah bin Sharik narrates that I heard from Hazrat Abdullah bin Umar (may Allah be pleased with them) that a person asked whether he could attend the funeral of his Christian mother who had passed away. He replied: Go with her, but walk ahead of her funeral procession.

Hazrat Saeed bin Jubair narrates that a Christian passed away and he had a Muslim son who did not participate in his funeral. Hazrat Abdullah bin Abbas (may Allah be pleased with them) said: It would have been appropriate for him to go with his father's funeral, bury him, and pray for his forgiveness during his (the father's) lifetime.

Hazrat Sha'bi narrates that when Abu Talib passed away, Hazrat Ali (may Allah be pleased with him, may Allah honor his face) came to the Holy Prophet (peace and blessings be upon him) and said, "Your disbelieving uncle has died. What is your opinion regarding him?" The Prophet (peace and blessings be upon him) said: "Give him a bath and bury him," and later instructed them to perform the washing.

Hazrat Saeed bin Jubair narrates that when a Christian man passed away, his son handed him over to the people of his own religion. When this was mentioned to Hazrat Abdullah bin Abbas (may Allah be pleased with them), he said: There would have been no harm if he had gone with him, buried him, and prayed for his forgiveness during his lifetime. Then he recited this verse: { وَمَا کَانَ اسْتِغْفَارُ إبْرَاہِیمَ لأَبِیہِ }.
