On the Day when Allāh will resurrect them all and inform them of what they did. Allāh had enumerated it, while they forgot it; and Allāh is, over all things, Witness. [Al Mujadilah:6]
This is one of the verses that really scare me and make me want to reform my actions. It is scary enough that we will stand before Allah (swt) but He will also inform us of what we have forgotten. If we try to mentally calculate every time we lied, cheated, backbit, and swore etc it is very hard. Sometimes we feel our bad deeds are little because we can’t remember all of them but the scary thing is that even those things we have forgotten about will come before us.
