A person died and Allah's Messenger (ﷺ) 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 (ﷺ) went to his grave and offered the (funeral) prayer.
