Riyad as-Salihin, 947

'Amr bin Al-'as (May Allah be pleased with him) used to say:

"When you have buried me, keep standing near my grave till (for the time it takes to) a camel is slaughtered and its meat is distributed, so that I may feel your nearness and know what to reply to the angels sent by my Rubb." <b>[Muslim]</b>.

وعن عمرو بن العاص رضي الله عنه قال‏:‏ إذا دفنتمونى، فأقيموا حول قبري قدر ما تنحر جذور، ويقسم لحمها حت أستأنس بكم، وأعلم ماذا أراجع به رسل ربي‏"‏ ‏(‏‏(‏رواه مسلم‏.‏ وقد سبق بطوله‏)‏‏)‏‏.‏ وقال الشافعي رحمه الله‏:‏ ويستحب أن يقرأ عنده شيء من القرآن، وإن ختموا القرآن عنده كان حسناً‏.‏

<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.
