Blind Following - Shaikh Faisal. Difference between Islam and kufr. From the moment Allah/s Messenger (saw) left this dunyaa the Muslim Ummah faced a decline in the level of understanding. The Messenger of Allah (saw) praised the first three generations after which he said there would be many liars, and indeed we find that over the generations there have been many innovations and deviations introduced into the Ummah. Evidence and blind following.
