Narrated Ibn `Abbas.: A person died and Allah's Apostle used to visit him. He died at night and (the people) buried him at night. In the morning they informed the Prophet (about his death). He said, "What prevented you from informing me?" They replied, "It was night and it was a dark night and so we disliked to trouble you." The Prophet went to his grave and offered the (funeral) prayer.

Narrated Sulaiman Ash-Shaibani: I heard Ash-Shu`bi saying, "A person who was accompanying the Prophet passed by a grave that was separated from the other graves told me that the Prophet once led the people in the (funeral) prayer and the people had aligned behind him. I said, "O Aba `Amr! Who told you about it?" He said, "Ibn `Abbas."
