مسند أحمد

It was narrated from al-Hasan bin Zaid bin Hasan: My father told me, from his father, that ‘Ali (رضي الله عنه) said: I was with the Prophet (ﷺ) when Abu Bakr and `Umar (رضي الله عنهما) came and he said: `O `Ali, these two are the leaders of the middle aged people of Paradise and its youth, after the Prophet (ﷺ) and Messengers.”
