We visited Khabbaba who said, "We migrated with the Prophet ﷺ for Allah's Sake, so our reward became due and sure with Allah. Some of us passed away without taking anything of their rewards (in this world) and one of them was Musʿab bin ʿUmar who was martyred on the day (of the battle) of Uhud leaving a striped woolen cloak. When we covered his head with it, his feet became naked, and when covered his feet, his head became naked. So Messenger of Allah ﷺ ordered us to cover his head and put some Idhkhir (i.e. a special kind of grass) on his feet. (On the other hand) some of us have had their fruits ripened (in this world) and they are collecting them." (Using translation from Bukhārī 3897)
هَاجَرْنَا مَعَ رَسُولِ اللهِ ﷺوَنَحْنُ نَبْتَغِي وَجْهَ اللهِ فَوَقَعَ أَجْرُنَا عَلَى اللهِ فَمِنَّا مَنْ مَضَى مِنْ قَبْلُ وَلَمْ يَأْكُلْ مِنْ أَجْرِهِ شَيْئًا كَانَ مِنْهُمْ مُصْعَبُ بْنُ عُمَيْرٍ قُتِلَ يَوْمَ أُحُدٍ وَلَمْ يَتْرُكْ إِلَّا نَمِرَةً فَكُنَّا إِذَا غَطَّيْنَا رَأْسَهُ بَدَتْ رِجْلَاهُ وَإِذَا غَطَّيْنَا رِجْلَيْهِ بَدَا رَأْسُهُ فَقَالَ رَسُولُ اللهِ ﷺغَطُّوا رَأْسَهُ وَاجْعَلُوا عَلَى رِجْلَيْهِ مِنَ الْإِذْخِرِ وَمِنَّا مَنْ أَيْنَعَتْ لَهُ ثَمَرَتُهُ فَهُوَ يَهْدِبُهَا
