and allah created you and then he will cause you to die and among you there are some who are sent back to senility so that they know nothing after having known . truly allah is knowing capable of all things.
والله خلقكم ثم يتوفاكم ومنكم من يرد إلى أرذل العمر لكي لا يعلم بعد علم شيئا إن الله عليم قدير
