Narrated Khabbab:Mus'ab b. 'Umar was killed at the battle of Uhud, and for him only a coarse cloth would be found as shroud. When we covered his head, his feet showed, and when we covered his feet, his head showed. So the Messenger of Allah (ﷺ) said: Cover his head with it (cloth), and put some rushes over his feet.
حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، أَخْبَرَنَا سُفْيَانُ، عَنِ الأَعْمَشِ، عَنْ أَبِي وَائِلٍ، عَنْ خَبَّابٍ، قَالَ مُصْعَبُ بْنُ عُمَيْرٍ قُتِلَ يَوْمَ أُحُدٍ وَلَمْ تَكُنْ لَهُ إِلاَّ نَمِرَةٌ كُنَّا إِذَا غَطَّيْنَا بِهَا رَأْسَهُ خَرَجَتْ رِجْلاَهُ وَإِذَا غَطَّيْنَا رِجْلَيْهِ خَرَجَ رَأْسُهُ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " غَطُّوا بِهَا رَأْسَهُ وَاجْعَلُوا عَلَى رِجْلَيْهِ مِنَ الإِذْخِرِ " .
