All that the believers say, when they are called to God and His Messenger, that he may judge between them, is that they say, 'We hear, and we obey'; those -- they are the prosperers. 51 for, they who pay heed unto God and His Apostle, and stand in awe of God and are conscious of Him, it is they, they who shall triumph [in the end]! 52 ۞ Now [as for those half-hearted ones,] they do swear by God with their most solemn oaths that if thou [O Apostle] shouldst ever bid them to do so, they would most certainly go forth [and sacrifice themselves]. Say: "Swear not! Reasonable compliance [with God's message is all that is required of you]. Verily, God is aware of all that you do!" 53 Say: "Obey Allah, and obey the Messenger: but if ye turn away, he is only responsible for the duty placed on him and ye for that placed on you. If ye obey him, ye shall be on right guidance. The Messenger's duty is only to preach the clear (Message). 54 Allah has promised those who have believed among you and done righteous deeds that He will surely grant them succession [to authority] upon the earth just as He granted it to those before them and that He will surely establish for them [therein] their religion which He has preferred for them and that He will surely substitute for them, after their fear, security, [for] they worship Me, not associating anything with Me. But whoever disbelieves after that - then those are the defiantly disobedient. 55 And establish prayer and give zakah and obey the Messenger - that you may receive mercy. 56 Deem not those who disbelieve able to frustrate His purpose on the earth; and their abode shall be the Fire - an ill retreat! 57
