The God does not forget anything
He created everything even the tiny pebble lost deep underground ... literally everything and also literally nothing happens without His permission
He does not need angels or anyone to record anything.. it is a system He created only
He needs nothing and no one
when He says He will forget the disbelievers and wrongdoers i understand He means He will not have mercy on them and will discard them
The God is the owner of ALL and EVERYTHING, there is just Him and none else and He knows everything including past present and future (it is He who permits the “future” to even happen)
so no, The God forgets nothing
and so we need to strive to do good even if it is the size of a pebble (but we should aim
to do good without limit with His permission

)... everything is known to Him
peace
