قَالَ عِلْمُهَا عِندَ رَبِّي فِي كِتَابٍ(Musa) said:"The knowledge thereof is with my Lord, in a Record.Musa said to him, in response to this, that if they did not worship Allah, then Allah knows precisely what happened to them and He will give them just recompense for their deeds, as is written in Allah's Book (of decrees). This Book is called Al-Lawh Al-Mahfuz (The Preserved Tablet) and it is the Book of Deeds.لاَّا يَضِلُّ رَبِّي وَلَا يَنسَىMy Lord neither errs nor forgets.This means that nothing eludes Him and He does not miss anything, whether it is small or great. He does not forget anything and His Most Exalted knowledge is described as encompassing everything. Blessed be He, the Exalted, the Most Holy and free of any imperfections.The knowledge that creatures have has two deficiencies. The first is that it does not completely encompass anything, and the second is that the creature is prone to forget after knowing. Therefore, Allah has declared Himself above such deficiencies
