Compiled by Imam Yahya ibn Sharaf al-Nawawi
وعن السائب بن يزيد رضي الله عنه، قال: حج بي مع رسول الله صلى الله عليه وسلم في حجة الوداع وأنا ابن سبع سنين. ((رواه البخاري)).
I was seven years old when I was taken to perform Hajj (pilgrimage). This was during the time the Messenger of Allah (ﷺ) performed the Hajjat-ul-Wada' (Farewell Pilgrimage).[Al- Bukhari].
