Imām Bukhārī narrates: Muslim ibn Ibrāhīm narrated to us, he said: Hishām narrated to us, he said: Yahyā ibn Abī Kathīr narrated to us, from Abī Qilābah, from Abī al-Malīh, he narrated that:
We were with Buraidah, may Allāh be pleased with him, on a cloudy day in a battle. He said: Pray the 'Asr prayer at its first time, because the Prophet ﷺ has said: Whoever abandons the 'Asr prayer, his deed is nullified.
