Hadith 2257
Sayyiduna Ali (may Allah be pleased with him) narrates: On the occasion of the Battle of Badr, besides Miqdad, none of us was mounted on a horse, and I remember, every one of us was standing. (Here, the wording of the narration has been incorrectly transmitted; the correct wording is: every one of us was asleep) Only the Prophet Muhammad (peace and blessings be upon him) (remained awake); he kept performing prayer under a tree and kept weeping until morning came.
