Allah has indeed bestowed a great favour upon the Muslims , in that He sent to them a Noble Messenger ( Prophet Mohammed peace and – blessings be upon him ) from among them , who recites to them His verses , and purifies them , and teaches them the Book and wisdom ; and before it , they were definitely in open error . ( The Holy Prophet Mohammed peace and – blessings be upon him – is one of Allah s ’ greatest favours to mankind . )
