Qur'an, Fussilat, Surah 48:26
In the case of those who say, "Our Lord is Allah," and, further, stand straight and steadfast, the angels descend on them (from time to time): "Fear ye not!" (they suggest), "Nor grieve! but receive the Glad Tidings of the Garden (of Bliss), the which ye were promised!
"We are your protectors in this life and in the Hereafter: therein shall ye have all that your souls shall desire; therein shall ye have all that ye ask for!"
