We have read in the preceding verses that God HAS created for MAN all that is on the earth. Verses from NO. 30 to NO. 39 give some details of three main important matters: 1) Informing the angels that HE is going to appoint a VICEGERENT (CALIPH) in the earth. 2) Commanding the angels to bow down and prostrate themselves before ADAM. 3) Describing the condition of ADAM in PARADISE, his fall from the GARDEN OF BLISS, then his repentance and turn-back, and finally his living with his children on the earth.
