Shaikh Uthaymeen said: ”Why would they not be from the most ignorant of people……!
In The Name of Allaah, The Most Merciful, The Bestower of Mercy
”And when it is said to them (hypocrites): “Believe as the people (followers of Muhammad Peace be upon him, Al-Ansar and Al-Muhajirun) have believed,” they say: “Shall we believe as the fools have believed?” Verily, they are the fools, but they know not.” [Soorah Al-Baqarah Ayah: 13]
Shaikh Muhammad Bin Saaleh Al-Uthaymeen (rahimahullaah) said:
From the benefits of the ayah is an indication to the ignorance of the hypocrites, because Allaah (The Mighty and Majestic) negated knowledge from them due to His saying:”But they know not.” The reality is that they are from the most ignorant of people. Why would they not be from the most ignorant of people!–for indeed their path is deception, manipulation and misguidance. These hypocrites are from the most ignorant of people because they do not know the reality about themselves and that they are foolish (people).
