Abu Aseeb or Abu Asim reported,

He witnessed the prayer over the Messenger of Allah ﷺ. The people asked, "How shall we pray over him?"He replied, "Enter in groups, one after another."So they would enter through one door, pray over him, and leave through the other door. When he was placed in his grave, Mughira said, "Something of his feet remains that they have not set right."They said, "Then go in and set it right."He entered and reached in his hand, touching the Prophet's feet. Then he said, "Pour the earth over me."So they poured earth over him until it reached the middle of his shins, then he came out. He used to say, "I am the one among you who had the most recent contact with the Messenger of Allah ﷺ."

Sahih

عن أبي عسيب، أو أبي عسيم

أنه شهد الصلاة على رسول الله ﷺ قالوا: كيف نصلي عليه؟ قال: ادخلوا أرسالا أرسالا، قال: فكانوا يدخلون من هذا الباب، فيصلون عليه، ثم يخرجون من الباب الآخر، قال: فلما وضع في لحده قال المغيرة: قد بقي من رجليه شيء لم يصلحوه، قالوا: فادخل فأصلحه، فدخل وأدخل يده، فمس قدميه، فقال: أهيلواعلي التراب، فأهالوا عليه التراب حتى بلغ أنصاف ساقيه، تم خرج، فكان يقول: أنا أحدثكم عهدا برسول الله ﷺ.
