The final messenger of Allah Prophet Muhammad (pbuh) mounted the pulpit, then wept and said, “Ask Allah (swt) for forgiveness and health, for after being granted certainty, one is given nothing better than health.”
-Related in Tirmidhi
Health is indeed a favour that we take for granted. We should express gratitude to Allah for bestowing us with health, and we should try our up most to look after it. Allah has entrusted us with our bodies for a predestined period of time. He will hold us to account on how we looked after and utilised our bodies and good health.
