Sayyiduna Jabir (may Allah be pleased with him) narrated a shortened report with the same meaning, at the end of which is: When the Muhajir saw the Ansari's blood, he said: 'Subhan Allah' (Glory be to Allah)! Why did you not tell me when he first shot (the arrow) at you? He said: I was reciting a surah and did not think it right to cut it off in the middle.
