عَنْ خَبَّابِ (بْنِ الْأَرَتِّ) رَضِيَ اللَّهُ عَنْهُ قَالَ: هَاجَرْنَا مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ نَبْتَغِي وَجْهَ اللَّهِ تَبَارَكَ وَتَعَالَى فَوَجَبَ أَجْرُنَا عَلَى اللَّهِ عَزَّ وَجَلَّ، فَمِنَّا مَنْ مَضَى لَمْ يَأْكُلْ مِنْ أَجْرِهِ شَيْئًا، مِنْهُمْ مُصْعَبُ بْنُ عُمَيْرٍ قُتِلَ يَوْمَ أُحُدٍ فَلَمْ نَجِدْ شَيْئًا نُكَفِّنُهُ فِيهِ إِلَّا نَمِرَةً كُنَّا إِذَا غَطَّيْنَا بِهَا رَأْسَهُ خَرَجَتْ رِجْلَاهُ، وَإِذَا غَطَّيْنَا رِجْلَيْهِ خَرَجَ رَأْسُهُ، فَأَمَرَنَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنْ نُغَطِّيَ بِهَا رَأْسَهُ وَنَجْعَلَ عَلَى رِجْلَيْهِ إِذْخِرًا، وَمِنَّا مَنْ أَيْنَعَتْ لَهُ ثَمَرَتُهُ فَهُوَ يَهْدِي بِهَا يَعْنِي يَجْتَنِيهَا
Sayyiduna Khabbab bin Al-Aratt (may Allah be pleased with him) says: We migrated with the Messenger of Allah (peace and blessings be upon him) for the pleasure of Allah Almighty, so our reward with Allah became assured (as He has promised). Then among us were some who departed to Allah without having consumed the reward of their deeds; among them was Sayyiduna Mus'ab bin Umair (may Allah be pleased with him), who was martyred on the day of Uhud. For his shroud, we could find only one sheet, and it was so short that when we covered his head, his feet became uncovered, and when we covered his feet, his head became uncovered. Eventually, the Messenger of Allah (peace and blessings be upon him) ordered us to cover his head and to place idhkhir (a type of grass) over his feet. While among us are also those whose fruits have ripened and now he is gathering them.
