All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.
There is no contradiction between Aadam being created from clay and him being created by the word of Allaah “Be”; his origin was clay and with the word “Be” he became a human being, a well-proportioned man. Allaah Says (what means): {...then We developed him into another creation.}[Quran 23:14]
As regards the Tablets of Moosa (Moses) they are the Torah itself, they are the Tablets on which Allaah has written the Torah. For more benefit, please refer to Fatwa ">12415.
As regards the details of the creation of Aadam then you may refer to Fataawa 91002 and 82792.
Allaah Knows best.
