23:30
إِنَّ فِى ذَٰلِكَ لَـَٔايَـٰتٍ وَإِن كُنَّا لَمُبْتَلِينَ
inna fī dhālika laāyātin wa-in kunnā lamub'talīna
There are signs in all this: We have always put [people] to the test.
Verily, in this [what We did as regards drowning of the people of Nûh (Noah)], there are indeed Ayât (proofs, evidence, lessons, signs, etc. for men to understand), for sure We are ever putting (men) to the test.
