Narrated 'Abdullah bin Az-Zubair:
that Az-Zubair said: On the Day of (the battle of) Uhud, the Messenger of Allah (ﷺ) wore two coats of mail. He tried to get up on a boulder, but was not able to, so Talhah squatted under him, lifting the Prophet (ﷺ) upon it, such that he could sit on the boulder. So he said: 'It (Paradise) is obligatory for Talhah.'
