Is the reward for good (anything) but good? (Quran 55:60)

And among His signs is that He created for you spouses from among yourselves that you may dwell in tranquility with them, and He has put love and mercy between you; verily, in that are signs for people who reflect.(Quran 30:21)

Surely with hardship is ease. So indeed, with the hardship (is) ease.(Quran 94:6)
