Assim al Hakeem is not a Scholar of Islam
A mere diploma holder from Islamic university does not grant anyone the rank of a Shaykh/Scholar of Islam!
Can any person imagine an actual upright salafi scholar insulting someones mother in such a manner ?
As for those saying:
"Akhi, he did so much good for Islam"
Response:
Allah may use a fasiq to aid and benefit the Deen.
It doesn't mean the person is no longer a fasiq (open rebellious sinful person).
Furthermore,
Is the celebrity muslim speaker being refuted for the good he did? His good is between him and Allah
As for the evil he makes apparent and public, he will be refuted for it in public!
So that his blind followers and sympathizers do NOT follow him in his ugly example and ill manners.
