And whomever Allah wills to guide, He opens his bosom for Islam; and whomever He wills to send astray, He makes his bosom narrow and firmly bound as if he were being forced by someone to climb the skies; this is how Allah places the punishment on those who do not believe.

So will you forsake part of what is divinely revealed to you and be disheartened because they say, “Why has not a treasure been sent down along with him?”, or “An angel should have come with him”? You are purely a Herald of Warning*; and Allah is the Guardian over all things. (* Therefore do not grieve over their sayings.)

And indeed We know that you are disheartened by their speech.

And O dear Prophet (Mohammed – peace and blessings be upon him) patiently endure – and your patience is only due to the guidance of Allah – and do not grieve for them, and do not be disheartened by their deceits.

And when they are thrown into a narrow place in it, bound in chains, they will pray for death in it.
