That mankind was created with the same faith, i.e, there is no God (supreme authority) except Him, is reflected at the time of a dire situation!

Verses 30-33 of Chapter 30

Therefore set your attention for obeying Allah, devoted solely to Him; the foundation set by Allah, upon which He created man; do not change what Allah has created; this is the proper religion - but most people do not know. Inclining towards Him - and fear Him, and keep the prayer established, and never be of the polytheists. Those who broke their religion into several parts and became different groups; every group is happy with what it has. And when some affliction reaches men, they pray to their Lord inclining towards Him - and when He gives them a taste of His mercy, thereupon a group among them begins setting up partners to their Lord!
