Hadith “Our Bodies Have Rights Upon Us"
It is indeed a gift and every human being knows it. Quran doesn’t mention the obvious facts of material world, for that, human intellect is enough and Allah relies on our intellect to make the right decision in this regard ( which experience and history suggests that most of us do ). Quran talks about matters of our success in the hereafter, for which, our intellect has no basis to reach a precise conclusion in this regard unless guided by God Hismelf.
