The Prophet ﷺ was wearing two coats of mail on the day of Uhud. He tried to climb up onto the rock but was unable to do so, so Talha crouched beneath him, and the Prophet ﷺ climbed up on him until he stood firmly on the rock.He said, "I heard the Prophet ﷺ say, 'Talha has earned it.'"
كان على النبي ﷺ درعان يوم أحد، فنهض إلى الصخرة فلم يستطع، فأقعد طلحة تحته، فصعد النبي ﷺ عليه، حتى استوى على الصخرة، فقال: سمعت النبي ﷺ يقول: أوجب طلحة.
It was narrated by Tirmidhi (1692), (3738), Ahmad (1417), Ibn Hibban (6979), Hakim (3/374), and Bayhaqi (6/370, 9/46) through various chains from Muhammad bin Ishaq, and it is found in his Sirah as recorded in Sirat bin Hisham (2/86). He said, Yahya bin Abbad bin Abdullah bin Zubayr narrated to me, from his father, from his grandfather Abdullah bin Zubayr, from Zubayr bin Awwam, and he mentioned it. The mention of his father is omitted from al-Ihsan, and its chain is hasan because of Muhammad bin Ishaq.Tirmidhi said, "This is a hasan gharib hadith, we do not know it except through the narration of Muhammad bin Ishaq." Hakim said, "This is a sahih hadith according to the criteria of Muslim."His statement, "Talha secured (it)," means that he performed a deed that secured Paradise for him. There are other hadiths on this subject mentioned in the book of jihad and military campaigns.
