Abdullah Ibn Mas’ood Radi Allahu Ta’ala Anhu said:

لو وضع علم عمر في كفة ميزان و وضع علم الناس في كفة لرجح علم عمر
“If the knowledge of ‘Umar was put on one side of a scale, and the knowledge of the people on the other side of the scale, ‘Umar’s knowledge would weigh more.” [Al-Mustadrak ‘ala al-Sahîhayn‎, Vol. 3, Page 92, Hadith 4497]

So who is Gareth Bryant to criticize Ameerulmumineen!
