(11) For these, there is hope that Allah will forgive: For Allah doth blot out (sins) and forgive again and again.

(12) Allah forgiveth not (The sin of) joining other gods with Him; but He forgiveth whom He pleaseth other sins than this: one who joins other gods with Allah, Hath strayed far, far away (from the right).

(13) Whether ye publish a good deed or conceal it or cover evil with pardon, verily Allah doth blot out (sins) and hath power (in the judgment of values).

(14) (Both) the Jews and the Christians say: "We are sons of Allah, and his beloved." Say: "Why then doth He punish you for your sins? Nay, ye are but men,- of the men he hath created: He forgiveth whom He pleaseth, and He punisheth whom He pleaseth: and to Allah belongeth the dominion of the heavens and the earth, and all that is between: and unto Him is the final goal (of all)"

(15) See they not how many of those before them We did destroy?- generations We had established on the earth, in strength such as We have not given to you - for whom We poured out rain from the skies in abundance, and gave (fertile) streams flowing beneath their (feet): yet for their sins We destroyed them, and raised in their wake fresh generations (to succeed them).

(16) How many towns have We destroyed (for their sins)? Our punishment took them on a sudden by night or while they slept for their afternoon rest.

(17) Say: the things that my Lord hath indeed forbidden are: shameful deeds, whether open or secret; sins and trespasses against truth or reason; assigning of partners to Allah, for which He hath given no authority; and saying things about Allah of which ye have no knowledge.

(18) To those who inherit the earth in succession to its (previous) possessors, is it not a guiding, (lesson) that, if We so willed, We could punish them (too) for their sins, and seal up their hearts so that they could not hear?

(19) Those who believe, and adopt exile, and fight for the Faith, in the cause of Allah as well as those who give (them) asylum and aid,- these are (all) in very truth the Believers: for them is the forgiveness of sins and a provision most generous.

(20) Not so do those who show patience and constancy, and work righteousness; for them is forgiveness (of sins) and a great reward.
