I heard the Messenger of Allah ﷺ say one day: ʿParadise is due to Talhah,ʿ when he did what he did for the Messenger of Allah ﷺ(i.e., when Talhah leaned down and the Messenger of Allah ﷺ climbed on his back.)
سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ يَوْمَئِذٍ أَوْجَبَ طَلْحَةُ حِينَ صَنَعَ بِرَسُولِ اللهِ ﷺ مَا صَنَعَ يَعْنِي حِينَ بَرَكَ لَهُ طَلْحَةُ فَصَعِدَ رَسُولُ اللهِ ﷺ عَلَى ظَهْرِهِ
