Reference: Related by Haakim with a continuous sanad up to Shaafi’ee, as in Taareekh Damishq of Ibn ‘Asaakir (15/1/3), I’laam al-Muwaqqi’een (2/363, 364) and Eeqaaz (p. 100)
Imaam ash-Shaafi’ee (rahima-hullaah) said:
The Sunnahs of the Messenger of Allaah ﷺ reach, as well as escape from every one of us. So whenever I voice my opinion, or formulate a principle, where something contrary to my view exists on the authority of the Messenger of Allaah ﷺ, then the correct view is what the Messenger of Allaah ﷺ has said, and it (that) is my view.
