وَعَنِ الزُّبَيْرِ قَالَ: كَانَ عَلَى النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَوْمَ أُحُدٍ دِرْعَانِ فَنَهَضَ إِلَى الصَّخْرَةِ فَلَمْ يَسْتَطِعْ فَقَعَدَ طَلْحَةُ تَحْتَهُ حَتَّى اسْتَوَى عَلَى الصَّخْرَةِ فَسَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «أَوْجَبَ طَلْحَةُ» . رَوَاهُ التِّرْمِذِيّ

Az-Zubair said

At the battle of Uhud the Prophet was wearing two coats of mail. He got up to go to the rock but was unable to climb up, so Talha let him step on his back and thus he was able to settle himself on the rock. I heard God's messenger say, "Talha has made [paradise certain for himself]." Tirmidhi transmitted it.
