Is the name of Malak allowed for Muslim?
Praise be to Allah, the Lord of the Worlds; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.
It is dislikeable to use such a name as “Malak” since this word denotes glorification and purification. It is reported in Saheeh Muslim that “The Prophet (Sallallahu Alaihi wa Sallam) rejected calling children with names like "Barrah" (righteous). The Prophet (Sallallahu Alaihi wa Sallam) said (commenting on such a name): "Do not give yourself a status that exceeds yours. Indeed, Allah Knows best the righteous people amongst you”. They asked what should we name her? He said: 'Give her the name of Zainab'”. So, you may use other appropriate names for a Muslim child.
Allah knows best.
