SHAFAQNA – Allah (SWT) sent a revelation to Prophet Isa/Jesus (AS): O’ Isa, either advise and preach yourself, or you should be ashamed of God for not practicing what you preach to other people . God also revealed to Prophet Dawood (AS): The easiest thing I do against those who do not practice/act according to their knowledge includes 70 inward punishments which will take away the enjoyment of Zikr from their hearts . In another revelation to Prophet Dawood (AS), Allah (SWT) said: O’ Dawood, do not place between yourself and God a scholar who loves the world, as he will stop you from your friendship with God, because these (types of scholars) are thieves in the way of the believing servants of God. The least I (God) will do to them is to take out of their hearts the pleasure of worshipping God .
