Riyad as-Salihin, 946

Abu `Amr (also called Abu `Abdullah and also Abu Laila) from `Uthman bin `Affan (May Allah be pleased with him) reported:

After the burial of a dead man, the Prophet (ﷺ) would stand by the grave and say, "Ask Allah to forgive your brother and supplicate for him for steadfastness because he is being questioned (about his deeds) now." <b>[Abu Dawud]</b>.

عن أبي عمرو -وقيل‏:‏ أبو عبد الله، وقيل‏:‏ أبو ليلى- عثمان بن عفان رضي الله عنه قال‏:‏ كان النبي صلى الله عليه وسلمى الله عليه وسلم الله عليه وسلم الله عليه وسلم إذا فرغ من دفن الميت وقف عليه، وقال‏:‏ ‏

‏استغفروا لأخيكم وسلوا له التثبيت، فإنه الآن يسأل‏

‏ ‏(‏‏(‏رواه أبو داود‏)‏‏)‏‏.‏

<b>Guidance from the Hadith:</b><br> 1) The Sunnah in burial is to ask Allah Almighty to forgive the dead person and make him firm during the questioning by the two angels.<br> 2) The trial of the grave is quite grave, and that is the questioning by the two angels. So, a dead person needs supplication by his fellow Muslims for him to stay firm.<br> Note:<br> His words “for he is being questioned now” give a certain piece of information by the Prophet (may Allah’s peace and blessings be upon him) at the time, as he knew, through revelation from his Lord, that the man was being questioned after the Prophet had finished the burial. In our time, however, the preacher should not say this phrase “for he is being questioned now”, as he does not know whether he is actually being questioned now or not. He should only say: “Ask forgiveness for your brother and implore Allah to make him firm.”
