Surah Al Mu'minun Tafseer

meaning, `you made fun of them for calling on Me and praying to Me,'

حَتَّى أَنسَوْكُمْ ذِكْرِي

so much so that they made you forget My remembrance,

means, your hatred for them made you forget what I would do to you.

وَكُنتُم مِّنْهُمْ تَضْحَكُونَ

while you used to laugh at them!

means, at their deeds and worship.

This is like the Ayah:

إِنَّ الَّذِينَ أَجْرَمُواْ كَانُواْ مِنَ الَّذِينَ ءَامَنُواْ يَضْحَكُونَ

وَإِذَا مَرُّواْ بِهِمْ يَتَغَامَزُونَ

Verily, those who committed crimes used to laugh at those who believed. And, whenever they passed by them, used to wink one to another. (83:29-30)

meaning, they used to slander them in mockery.

Then Allah tells us how He will reward His friends and righteous servants, and says
