The story
Twice the Qur'an opens its registers of honor and includes a name wrapped in quiet: Dhul-Kifl. With Ismail and Idris he is counted 'of the patient' and admitted 'into Our mercy' (21:85-86); with Ismail and Alyasa he is 'of the excellent' (38:48). His very name means the possessor of a pledge or portion, and the commentators tell of a righteous man who guaranteed to fast the days, stand the nights, and judge the people without anger, and who kept the guarantee.
The Codex keeps to what the Book states: patience, righteousness, mercy, excellence. Some scholars count him a prophet, others a saint among Bani Israil. Either way his lesson is complete: heaven records the keepers of commitments, even when history loses their files.
