Al-Mani'
Allah is Al-Maani, The One who withholds bounty from those undeserving. Allah protects people from harmful situations and prevents undesirable actions. He can withhold His light from those who deliberately reject Him.
From the root m-n-‘ which has the following classical Arabic connotations: to prevent, hinder, hold back, restrain, deny impeding, resist to forbid, refuse, prohibit to guard, defend, protect.
Or who is it that could provide for you if He withheld His provision? But they have persisted in insolence and aversion. (Quran 67:21)
Indeed, Allah defends those who have believed. Indeed, Allah does not like everyone treacherous and ungrateful. (Quran 22:38)
And what Allah restored to His Messenger from the people of the towns – it is for Allah and for the Messenger and for [his] near relatives and orphans and the [stranded] traveler – so that it will not be a perpetual distribution among the rich from among you. And whatever the Messenger has given you – take;
and what he has forbidden you – refrain from. And fear Allah;
indeed, Allah is severe in penalty. (Quran 59:7)
