The response of the believers, when they are invited to Allah and His Apostle that he may judge between them, is only to say: We hear and we obey; and these it is that are the successful. 51 And he who obeys Allah and His Apostle, and fears Allah, and is careful of (his duty to) Him, these it is that are the achievers. 52 ۞ They swear by Allah their strongest oaths, that if only you would order them, they would leave (their homes for fighting in Allah's Cause). Say: "Swear you not; (this) obedience (of yours) is known (to be false). Verily, Allah knows well what you do." 53 Say: 'Obey God, and obey the Messenger; then, if you turn away, only upon him rests what is laid on him, and upon you rests what is laid on you. If you obey him, you will be guided. It is only for the Messenger to deliver the manifest Message.' 54 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. 55 Hence, [O believers,] be constant in prayer, and render the purifying dues, and pay heed unto the Apostle, so that you might be graced with God's mercy. 56 Never think that the disbelievers are causing failure [to Allah] upon the earth. Their refuge will be the Fire - and how wretched the destination. 57
