Allah (swt) shows us how He can create man without male or female – He created Adam (as) from dust.
Allah shows us how He can create woman without a female – He created Eve (as) from the rib of man.
And lastly Allah shows us how He can create man without a male – He created Jesus (as).
That is Allah. Nothing is difficult for Allah for He just says “Be, and it is” – Subhanallah
