42:29 And among His signs is the creative design of the heavens and the earth, and the living creatures which He has dispersed throughout them. And He is Able to gather them together when He wills. [Here is an allusion to the existence of life in other celestial bodies, and to man meeting with the 'aliens' someday. 16:49]
Dear brother, Wa Salam O Rahmat!
I am delighted to see your knowledge of Allama Iqbal :-) At different stages of his life, the great Allama did lean towards Sufism when he got impressed with his "Pir-e-Rumi".
I count "Maulana' Rumi among the Criminals of Islam. One example: He says,
MAA ZE QUR'AN MAGHZ RA BARDASHTAIM
ISTAKHWAN PESH-E SAGAAN ANDAKHTAIM
He considers and declares other Muslims as dogs!
