know may Allah have mercy on you that we Muslims are obligated to learn 4 matters
firstly Knowledge ; which means awareness of Allah awareness of his prophet awareness of the religion of Islam based on the evidence
secondly Acting on it
third Calling to it
fourth Patiences with the harm that befalls due to it
Indeed, mankind is in loss,
Except for those who have believed and done righteous deeds and advised each other to truth and advised each other to patience.
