Tafsir of Al Imran 3:141

وليمحص الله الذين آمنوا

And Allah likes not the wrongdoers. And that Allah may test those who believe, by forgiving them their sins if they have any. Otherwise, Allah will raise their grades according to the losses they suffered. Allah's statement,

ويمحق الكافرين

and destroy the disbelievers. for it is their conduct that if they gain the upper hand, they transgress and commit aggression. However, this conduct only leads to ultimate destruction, extermination, perishing and dying out. Allah then said,

أم حسبتم أن تدخلوا الجنة ولما يعلم الله الذين جاهدوا منكم ويعلم الصابرين
