All Prophets and Messengers were Humans

Allah says, `Just as We have sent you O Muhammad, a Prophet and a human, We sent the Messengers before you from among mankind, that eat food, walk in the markets, and We gave them wives and offspring.' Allah said to the most honorable and Final Messenger,

قُلْ إِنَّمَآ أَنَاْ بَشَرٌ مِّثْلُكُمْ يُوحَى إِلَىَّ

Said in the next verse (39) was: يَمْحُو اللَّـهُ مَا يَشَاءُ وَيُثْبِتُ ۖ وَعِندَهُ أُمُّ الْكِتَابِ : 'Allah wipes off what He wills and affirms (what He wills). And with Him is the Mother Book.' [ The translation of: أُمُّ الْكِتَابِ (umm-ul-kitab) as 'Mother Book' reflects a word for word replacement possible at this place which also exhudes its applied sense in some measure, though not as clearly as given in the Tafsir immediately after ] The literal meaning of 'Umm al-Kit' is 'The Original Book.' The reference here is to the 'Preserved Tablet' (al-Lawh al-Mahfuz al-) in which there can be no change or alteration.

The sense of the verse is that Allah Ta’ ala, in His most perfect power and wisdom, obliterates what He wills, and affirms what He wills. And after this obliteration and affirmation, whatever there is stays preserved with Allah Ta’ ala. No one has access to it, nor can there be any deletion and addition into it.
