salaam,
Why the person do not depend his true creator if he really believes that there is a creator behind his existence & sustenance who is Just to all of His creation and capable of anything at anytime?
Why the creator made him/her abnormal?
Ponder over verses like 24:61.
Note that diseases/disabilities not mentioned in 2:155.
Examples of healing diseases/disabilities/defects in the Qur’an (3:49, 5:110)
17:89 And We have dispatched to the people in this Qur’an from every example, but most of the people refuse except (insisting) disbelief! (also 18:54, 30:58)
There is no specific mentioning of medicines/physicians/surgery etc. in the Qur’an, while diseases/illnesses/disabilities etc. mentioned! The Qur’an says it is complete.
Also, 31:17, 2:45-46, 153 etc.
Whatever scientific/technological developments we have, all these are happened/happening without having a proper understanding of the basics of our existence! I.e. even after all these interesting advancements, the so called ‘evolved humans’ are still not able to find a satisfactory explanation for ‘life’ and ‘death’.
The conditions of earth became/becoming worse than ever. Still, we think we are evolving!
