It is narrated from Ziyad bin Hudair that Sayyiduna Umar (may Allah be pleased with him) said to me: Do you know what will destroy Islam? I said: No. He said: The mistake of a scholar, the argument or debate of a hypocrite in the Book of Allah, and the command of misguided leaders. (That is, the mistake of a scholar, the debate of a hypocrite, and the command of misguided imams or rulers will destroy Islam, it will demolish its structure.)
