It is that of which Allah gives good tidings to His servants who believe and do righteous deeds. Say, [O Muhammad], " I do not ask you for it any payment only good will through kinship." And whoever implements a good deed - We will increase for him good therein. Indeed, Allah is Forgiving and Appreciative. Or do they say, " He has invented Allah a lie"? But if Allah willed, He could seal over your heart. And Allah eliminates falsehood and establishes the truth by his words. Indeed, He is knowing of that within the breasts. And it is He who accepts, repentance from His servants and pardon misdeeds, and He knows what you do. And He answers those who have believed and done righteous deeds and increases [for] them from His bounty. But the disbelievers will have a severe punishment. And if Allah had extended [excessively] provision for His servants, they would have committed tyranny throughout the earth. But He sends [it] down in an amount which He wills. Indeed He is, of His servants, Aware and seeing.
