لَّيۡسَ عَلَيۡكَ هُدَىٰهُمۡ وَلَٰكِنَّ ٱللَّهَ يَهۡدِى مَن يَشَآءُ ۗ وَمَا تُنفِقُواْ مِنۡ خَيۡرٍ فَلِأَنفُسِكُمۡ ۚ وَمَا تُنفِقُونَ إِلَّا ٱبۡتِغَآءَ وَجۡهِ ٱللَّهِ ۚ وَمَا تُنفِقُواْ مِنۡ خَيۡرٍ يُوَفَّ إِلَيۡكُمۡ وَأَنتُمۡ لَا تُظۡلَمُونَ
It is not required of thee (O Messenger), to set them on the right path, but Allah sets on the right path whom He pleaseth. Whatever of good ye give benefits your own souls, and ye shall only do so seeking the "Face" of Allah. Whatever good ye give, shall be rendered back to you, and ye shall not Be dealt with unjustly.<br/>
When the Prophet may peace and salutation be upon him was prohibited from giving voluntary alms to idolaters [as an incentive] for them to embrace Islam, the following was revealed: You are not responsible for guiding them, that is to say, for people, that they should embrace Islam, [you are responsible] only for conveying the Message [to them]; but God guides, with His guidance, whomever He will, to embrace Islam. And whatever good, property, you expend is for yourselves, since the reward is for you; for then you are expending, desiring only God's Face (this clause is the predicate, denoting a prohibition), that is to say, His reward and not any other transient object of this world, and whatever good you expend, its requital, shall be repaid to you in full, and you will not be wronged, you will not suffer any diminishment of it (both [of the last two] sentences emphasise the first one).
