Allah has created every animal of water, and some of them go upon their bellies, and some of them go upon two feet, and some of them go upon four; Allah creates whatever Hu will; Allah is powerful over everthing. (Qu’ran 24:45)

You should value the following: youth before old age, health before illness, being free before getting busy, life before death, and affluence before poverty.

(attributed to Rasulullah sallallaahu alayhi wasallam in mishkat ul-anwar #924)
