Ahmed Raza Khan: Mohammed Aqib Qadri:
It is not your duty (O dear Prophet Mohammed - peace and blessings be upon him) to make them accept guidance - but Allah guides whomever He wills; and whatever good thing you spend is beneficial for yourselves; and it is not right for you to spend except to seek Allah's pleasure; and whatever you spend will be repaid to you in full, and you will not be wronged. -

Yusuf Ali:
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.

Pickthal:
The guiding of them is not thy duty (O Muhammad), but Allah guideth whom He will. And whatsoever good thing ye spend, it is for yourselves, when ye spend not save in search of Allah's Countenance; and whatsoever good thing ye spend, it will be repaid to you in full, and ye will not be wronged.
