Umar ibn Abdul Aziz: The Prophet is a caller to Allah, not a tax collector

Ibn Kathir reported: Umar ibn Abdul Aziz (d. 101H/720CE) said, “Indeed, Allah has only sent Muhammad, peace and blessings be upon him, as a preacher and He did not send him as a tax collector.”

[Ibn Kathir, Al-Bidayah wa An-Nihayah 667]

قال عمر بن عبد العزيز إن الله إنما بعث محمدا صلى الله عليه وسلم داعيا ولم يبعثه جابيا
