?–644 CE · Second Rashidun caliph
Umar ibn al-Khattab
Umar's rulings on land taxation (kharaj) in conquered territories and his suspension of the hadd punishment for theft during famine are frequently cited as early instances of caliphal discretionary legal judgment (ra'y) rather than transmission of a specific Prophetic report. Later sources also credit his administration with appointing Umm al-Shifa bint Abdullah to a supervisory role over the Medina market, though the chain of transmission for that specific report is rated weak by classical hadith critics.
