He hath instituted for you in religion that which He had enjoined upon Nuh, and which We have revealed Unto thee, and which We had enjoined upon Ibrahim and Musa and Isa, saying: establish the religion, and be not divided therein. Grievous Unto the associaters is that Unto which thou callest them. Allah chooseth for Himself whomsoever He will and guideth Unto Himself whomsoever turneth in penitence.
