Dhul-Kifl (peace be upon him) is mentioned in the Qur'an alongside Isma'il and Idris, all of whom were among the patient (21:85). Allah admitted them into His mercy, for they were among the righteous (21:86).
He is also named among Isma'il and Al-Yasa', all counted among the best of people, the chosen (38:48). Beyond these affirmations of his patience and righteousness, the Qur'an provides no detailed narrative of his life.
In keeping with authenticity, only what Allah has affirmed about him is retained: that he was patient, righteous, chosen, and among those admitted into Allah's mercy. Later stories that add detail to his life are unverified and are therefore omitted.
Dhul-Kifl is named twice in the Quran among the patient and the righteous: "And [mention] Ismaʿil and Idris and Dhul-Kifl; all were of the patient" (21:85), and "remember Ismaʿil, al-Yasaʿ and Dhul-Kifl; all are among the outstanding" (38:48). Beyond this, no detailed story of his stands upon an authentic hadith, and scholars even differ over whether he was a prophet or a righteous man. On the way of the Salaf, we affirm what Allah affirmed — his patience and excellence — and leave what has no sound source, rather than fill the gap with unverified stories.
Stories are drawn from the Quran and authentic hadith; unverified narrations (
isra'iliyyat) and folk embellishments are avoided. For deeper study, consult the tafsir and a qualified scholar.
