On the Authority of Al-Hussain ibn Al-Hasan Al-Maroozee who said: I heard ibnul Mubaarak say:
“The people of the dunya exited the dunya before tasting the sweetest of that which is in it. It was said to him, and what is the sweetest of that which is in it?
He said: Ma’rifatu Allah – azza wa jal – (knowledge and awareness of Allah).”
