We migrated with the Messenger of Allah ﷺ in the cause of Allah, seeking the pleasure of Allah, so our reward fell due upon Allah. Among us were those who passed on without taking anything from their reward. One of them was Musab bin Umayr, who was killed on the day of Uhud. Nothing could be found to shroud him in except a striped cloak. When we placed it over his head, his feet were exposed, and when we placed it over his feet, his head was exposed. So the Messenger of Allah ﷺ said, "Place it over his head and put idhkhir grass over his feet." And among us were those whose fruit had ripened, and they were busy gathering it.
هاجرنا مع رسول الله ﷺ في سبيل الله، نبتغي وجه الله فوجب أجرنا على الله، فمنا من مضى لم يأكل من أجره شيئا، منهم مصعب بن عمير قتل يوم أحد، فلم يوجد له شيء يكفن فيه إلا نمرة، فكنا إذا وضعنا على رأسه خرجت رجلاه، وإذا وضعنا على رجليه خرج رأسه فقال رسول الله ﷺ: ضعوها مما يلي رأسه واجعلوا على رجليه الإذخر ومنا من أينعت له ثمرته فهو يهديها.
Bukhari narrated it in the Book of Funerals (1276), and Muslim narrated it in the Book of Funerals (940), both through the route of Amash, from Shaqiq, from Khabab bin Arat, who mentioned it, and their wordings are the same. His saying, "ripened" means it became ripe. And his saying, "he plucks it" means he gathers it.
