Sayyiduna Anas (may Allah be pleased with him) said that Sayyiduna Abu Talhah (may Allah be pleased with him) recited this verse: "Go forth, light or heavy" [Surah al-Tawbah: 41], and said: I see that our Lord has called upon both the old and the young to go forth in it. Then he said to his sons: O my sons, prepare me, prepare me. His sons said: You have indeed taken part in campaigns with the Messenger of Allah (peace and blessings be upon him), Abu Bakr and Umar (may Allah be pleased with them both); (now stay back) and we will fight. He said: Prepare me. Then he travelled by sea and died. (Sayyiduna Anas (may Allah be pleased with him) said:) They found an island only after seven days, so they buried him there, and his body remained completely unchanged.
