The Avenger, The Disapprover, The Inflictor of Retribution
The One who disapproves of wrongdoers. The One who reminds us when our behavior is not right.
The One who is the avenger (such that we need not seek any personal revenge).
The One and Only One who has the right to exact vengeance.
From the root n-q-m which has the following classical Arabic connotations:
to dislike, disapprove, find fault
to punish, exact vengeance
to inflict retribution, avenge
Therefore do not think Allah (to be One) failing in His promise to His prophets; surely Allah is Mighty, Lord of retribution" (Qur’an, 14:47).
Al-Muntaqim, the Avenger, splits the spines of those who deviate from His path, Who increases the penalty of those who oppress in the land, after alerting them and repeatedly warning them, and after enabling them to amend, giving them a respite. It implies a much more severe penalty than merely an immediate one.
Wallahu ta’alaa ‘alem.
And Allah knows Best.
