The only response of believers, whenever they are summoned unto God and His Apostle in order that [the divine writ] might judge between them, can be no other than, "We have heard, and we pay heed!" - and it is they, they who shall attain to a happy state: 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 ۞ And they swore by Allah most vehemently in their oaths that if you order them, they will go forth to holy war; say, “Do not swear; obedience according to the law is required; indeed Allah knows what you do.” 53 Say: "Obey God and obey the Apostle. If you turn away, then for him is his duty to fulfil, and for you the burden that you carry; yet if you obey him you will be rightly guided. The duty of the Messenger is to convey the message clearly. 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 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 unbelievers will be able to frustrate (Us) in the earth. Their refuge is the Fire, an evil arrival. 57
