Kharijah bin Zayd bin Thabit narrates from his paternal uncle Yazid bin Thabit (may Allah be pleased with him) that: One day they went out with the Messenger of Allah (peace and blessings be upon him) for a funeral until they reached al-Baqi'. He (peace and blessings be upon him) (seeing a new grave) asked: "What is this?" The people said: This is so-and-so, the freed slave-woman of such-and-such a tribe. He (peace and blessings be upon him) recognised her and said: "Why did you not inform me about her?" They said: We buried her at the time of Zuhr, and you were taking your midday rest (qaylulah) at that time, so we did not like to trouble you. So he (peace and blessings be upon him) stood, and the people formed rows behind him, and he (peace and blessings be upon him) said four takbirs over her. Then he said: "Whenever anyone among you dies, be sure to inform me, for my prayer is a mercy for them."
