Sahih Muslim 2471 b
Jabir b. 'Abdullah reported:
My father fell as a martyr on the Day of Uhud and I attempted to uncover his face and weep, but they (the Companions of the Holy Prophet) forbade me to do this, whereas Allah's Messenger (ﷺ) did not forbid me and Fatima bint Amr, the sister of my father, was also weeping There- upon Allah's Messenger (ﷺ) said: You may weep or you may not weep; the Angels provide him shade with the help of their wings until you lift him (to be buried in the grave).
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا وَهْبُ بْنُ جَرِيرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ مُحَمَّدِ بْنِ الْمُنْكَدِرِ،
 عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، قَالَ أُصِيبَ أَبِي يَوْمَ أُحُدٍ فَجَعَلْتُ أَكْشِفُ الثَّوْبَ عَنْ وَجْهِهِ، وَأَبْكِي،
 وَجَعَلُوا يَنْهَوْنَنِي وَرَسُولُ اللَّهِ صلى الله عليه وسلم لاَ يَنْهَانِي - قَالَ - وَجَعَلَتْ فَاطِمَةُ
 بِنْتُ عَمْرٍو تَبْكِيهِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏
"‏ تَبْكِيهِ أَوْ لاَ تَبْكِيهِ مَا زَالَتِ الْمَلاَئِكَةُ
 تُظِلُّهُ بِأَجْنِحَتِهَا حَتَّى رَفَعْتُمُوهُ ‏"‏ ‏.‏
