Assalamu Alaikum Warahmatullahi Wabarakatuh,

This thread is about what we should prioritise in order to keep our iman safe

First and foremost we must make sure that we are not doing anything (doing by action or by belief or by the lack of belief) that is kufr or shirk as these two will nullify our iman and render the rest of our efforts for deen null and void too

Secondly we must be careful to avoid and not transgress into bidah as bidah will land us in the hellfire temporarily and believe you me, we do not want to be in hellfire for even a second as that will be like the greatest punishment ever.

And last but not least, we should not hurt or offend our fellow Muslims and fellow bani-adam (this includes all of the non Muslims too) as this will nullify our ibadah too in the sense that we'll just have to pay it all as compensation to the people who we've wronged on the day of Judgement

May Allah make it easy for us, Ameen
