Compiled by Imam Muhammad al-Bukhari
حَدَّثَنَا عُمَرُ بْنُ حَفْصِ بْنِ غِيَاثٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا الأَعْمَشُ، حَدَّثَنَا شَقِيقٌ، حَدَّثَنَا خَبَّابٌ ـ رضى الله عنه ـ قَالَ هَاجَرْنَا مَعَ النَّبِيِّ صلى الله عليه وسلم نَلْتَمِسُ وَجْهَ اللَّهِ، فَوَقَعَ أَجْرُنَا عَلَى اللَّهِ، فَمِنَّا مَنْ مَاتَ لَمْ يَأْكُلْ مِنْ أَجْرِهِ شَيْئًا مِنْهُمْ مُصْعَبُ بْنُ عُمَيْرٍ، وَمِنَّا مَنْ أَيْنَعَتْ لَهُ ثَمَرَتُهُ فَهُوَ يَهْدِبُهَا. قُتِلَ يَوْمَ أُحُدٍ، فَلَمْ نَجِدْ مَا نُكَفِّنُهُ إِلاَّ بُرْدَةً إِذَا غَطَّيْنَا بِهَا رَأْسَهُ خَرَجَتْ رِجْلاَهُ، وَإِذَا غَطَّيْنَا رِجْلَيْهِ خَرَجَ رَأْسُهُ، فَأَمَرَنَا النَّبِيُّ صلى الله عليه وسلم أَنْ نُغَطِّيَ رَأْسَهُ، وَأَنْ نَجْعَلَ عَلَى رِجْلَيْهِ مِنَ الإِذْخِرِ.
We emigrated with the Prophet (p.b.u.h) in Allah's cause, and so our reward was then surely incumbent on Allah. Some of us died and they did not take anything from their rewards in this world, and amongst them was Mustab bin `Umar; and the others were those who got their rewards. Mustab bin `Umar was martyred on the day of the Battle of Uhud and we could get nothing except his Burd to shroud him in. And when we covered his head his feet became bare and vice versa. So the Prophet (ﷺ) ordered us to cover his head only and to put idhkhir (a kind of shrub) over his feet.
