"O ye that believe! fear Allah and believe in His apostle and He will bestow on you a double portion of His Mercy: He will provide for you a light by which ye shall walk (straight in your path) and He will forgive you (your past): For Allah is Oft-Forgiving. Most Merciful:
That the People of the Book may know that they have no power whatever over the Grace of Allah that (His) Grace is (entirely) in his hand to bestow it on whomsoever He wills. For Allah is the Lord of Grace abounding."
(Qur'an 57:28-29 : Surah Al-Hadid (The Iron))
