Abu Waail reported,

We visited Khababa, and he said, "We migrated with the Prophet ﷺ seeking the pleasure of Allah, so our reward became due upon Allah. Among us were those who passed away without taking any of their reward in this world. One of them was Musab bin Umayr, who was killed on the day of Uhud and left behind only a striped cloak. When we covered his head with it, his feet became exposed, and when we covered his feet, his head became exposed. So the Prophet ﷺ instructed us to cover his head and place some idhkhir grass over his feet. And among us are those whose fruit has ripened, and they are now harvesting it."

أبا وائل قال

عدنا خبابا فقال هاجرنا مع النبي ﷺ نريد وجه الله فوقع أجرنا على الله فمنا من مضى لم يأخذ من أجره منهم مصعب بن عمير قتل يوم أحد وترك نمرة فإذا غطينا رأسه بدت رجلاه وإذا غطينا رجليه بدا رأسه فأمرنا النبي ﷺ أن نغطي رأسه ونجعل على رجليه شيئا من الإذخر ومنا من أينعت له ثمرته فهو يهدبها
