Mus‘ar said: Ma‘n bin ‘Abdur Rahman brought out a book for me and swore that it was written in the handwriting of his father. I saw that it was written in it: It is narrated from ‘Abdullah, he said: By Him besides whom there is no deity, I have not seen anyone more severe and harsh upon those who go to extremes than the Messenger of Allah (peace be upon him), then I have not seen anyone more severe upon them than Sayyiduna Abu Bakr (may Allah be pleased with him), and now I am seeing Sayyiduna ‘Umar (may Allah be pleased with him) that there is no one who fears them or makes others fear them more than him.
