(12) And at the time when the hour shall come the guilty shall be in despair.

(13) And when We make people taste of mercy they rejoice in it, and if an evil befall them for what their hands have already wrought, lo! they are in despair.

(14) Though they were before this, before it was sent down upon them, confounded in sure despair.

(15) Say: O my servants! who have acted extravagantly against their own souls, do not despair of the mercy of Allah; surely Allah forgives the faults altogether; surely He is the Forgiving the Merciful.

(18) It shall not be abated from them and they shall therein be despairing.

(19) O you who believe! do not make friends with a people with whom Allah is wroth; indeed they despair of the hereafter as the unbelievers despair of those in tombs.

(20) And (as for) those of your women who have despaired of menstruation, if you have a doubt, their prescribed time shall be three months, and of those too who have not had their courses; and (as for) the pregnant women, their prescribed time is that they lay down their burden; and whoever is careful of (his duty to) Allah He will make easy for him his affair.
