And We divided them into twelve tribes, as nations; and We revealed to Musa when his people asked him for water: Strike the rock with your staff, so outnowed from it twelve springs; each tribe knew its drinking place; and We made the clouds to give shade over them and We sent to them manna and quails: Eat of the good things We have given you. And they did not do Us any harm, but they did injustice to their own souls.

Say: I do not control any benefit or harm for my own soul except as Allah please; and had I known the unseen I would have had much of good and no evil would have touched me; I am nothing but a warner and the giver of good news to a people who believe.

This is because Allah has never changed a favor which He has conferred upon a people until they change their own condition; and because Allah is Hearing, Knowing;

Surely your Lord knows that you pass in prayer nearly two-thirds of the night, and (sometimes) half of it, and (sometimes) a third of it, and (also) a party of those with you; and Allah measures the night and the day. He knows that you are not able to do it, so He has turned to you (mercifully), therefore read what is easy of the Quran. He knows that there must be among you sick, and others who travel in the land seeking of the bounty of Allah, and others who fight in Allah's way, therefore read as much of it as is easy (to you), and keep up prayer and pay the poor-rate and offer to Allah a goodly gift, and whatever of good you send on beforehand for yourselves, you will find it with Allah; that is best and greatest in reward; and ask forgiveness of Allah; surely Allah is Forgiving, Merciful.
