Muqatil
Yes. Muqatil ibn Sulayman is a historically attested early exegete (mufassir) referenced in classical bibliographies; the personal name Muqatil is recorded in early Islamic sources.
No. The name Muqatil itself does not appear in the Quran; it is a classical Arabic formation from the root q-t-l.
The root q-t-l relates to fighting or killing, so Muqatil conveys 'fighter' or 'combatant'. In historical contexts it can be an occupational or descriptive name; cultural sensitivity is advised depending on community norms.
No. Muqatil is very rare in contemporary naming; it is primarily encountered in historical texts and specialized onomastic studies.
It appears in early biographical and exegetical literature, sometimes as an epithet for warriors or as a personal name in classical Arabic sources.
