Allah hath promised those of you who believe and work the righteous works that he shall make them successors on the earth even as He had made those before them successors, and that he shall surely establish for them their religion which He hath approved for them, and that he shall surely exchange unto them after their fear a security, provided they worship Me, associating not aught with Me; and whosoever will disbelieve thereafter, then those! they are the transgressors.
