Imam Ad-Dhahabi [رحمه الله] said:
«لا خير إلا في الاتباع ، ولا يمكن الاتباع إلا بمعرفة السنن.»
❝There is no goodness except in following the Prophet and it is not possible to follow the Prophet without knowing the Sunnan [plural of Sunnah].❞
[Seera Alaam An-Nubala, (9/409) | Translated By Abbas Abu Yahya Miraath Al-Anbiyya]
