Quran on Anxiety

Saying: Lo! of old, when we were with our families, we were ever anxious;

Then, after grief, He sent down security for you. As slumber did it overcome a party of you, while (the other) party, who were anxious on their own account, thought wrongly of Allah, the thought of ignorance. They said: Have we any part in the cause? Say (O Muhammad): The cause belongeth wholly to Allah. They hide within themselves (a thought) which they reveal not unto thee, saying: Had we had any part in the cause we should not have been slain here. Say: Even though ye had been in your houses, those appointed to be slain would have gone forth to the places where they were to lie. (All this hath been) in order that Allah might try what is in your breasts and prove what is in your hearts. Allah is Aware of what is hidden in the breasts (of men).

And guard yourselves against a day when no soul will in aught avail another, nor will intercession be accepted from it, nor will compensation be received from it, nor will they be helped.

It is but a brief comfort. And afterward their habitation will be hell, an ill abode.

When He made the slumber fall upon you as a reassurance from him and sent down water from the sky upon you, that thereby He might purify you, and remove from you the fear of Satan, and make strong your hearts and firm (your) feet thereby.

As they come hurrying on in fear, their heads upraised, their gaze returning not to them, and their hearts as air.

And whatever of comfort ye enjoy, it is from Allah. Then, when misfortune reacheth you, unto Him ye cry for help.

And speak unto him a gentle word, that peradventure he may heed or fear.

With hearts preoccupied. And they confer in secret. The wrong-doers say: Is this other than a mortal like you? Will ye then succumb to magic when ye see (it)?

We give them comfort for a little, and then We drive them to a heavy doom.

It is not relaxed for them, and they despair therein.

Who feareth the Beneficent in secret and cometh with a contrite heart.

Lo! the doom of their Lord is that before which none can feel secure -

Leave Me to deal with the deniers, lords of ease and comfort (in this life); and do thou respite them awhile.

Every man that day will have concern enough to make him heedless (of others).

So give a respite to the disbelievers. Deal thou gently with them for a while.
