Talha's Helping the Prophet

During the withdrawal of the Messenger of Allâh [pbuh] up to the cover of the mountain, a big rock blocked his way. The Prophet [pbuh] tried to mount it, but having worn a short heavy armour, and being seriously wounded — he could not ascend it. Readily enough Talha sat in a position that enabled the Prophet [pbuh] to stand on his back. Then he lifted him up till he stood on it. The Prophet [pbuh] then said: "Talha, after this job, is eligible for the Garden (Paradise)."[Ibn Hisham 2/86]
