Abu Rabi’ says: I was with Sayyiduna Abdullah bin Umar (may Allah be pleased with him) at a funeral, when he heard the sound of a man crying out loudly, so he sent a message to him and had him silenced. I said: O Abdur Rahman! Why did you have him silenced? He said: Crying in this manner causes pain to the deceased until he is placed in the grave. Then I said: I pray Fajr with you, and when I finish this prayer (because of the darkness) I cannot see the face of the one sitting next to me, but sometimes it happens that you make light? He said: I saw the Messenger of Allah (peace and blessings be upon him) do the same, and I like to pray this prayer in the same way as I saw the Messenger of Allah (peace and blessings be upon him) pray it.
