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 whosoever obeyeth Allah and His apostle, and dreadeth Allah and feareth Him - these! they are the achievers. 52 ۞ And they swear by Allah with the most energetic of their oaths that if you command them they would certainly go forth. Say: Swear not; reasonable obedience (is desired); surely Allah is aware of 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 God has promised the righteously striving believers to appoint them as His deputies on earth, as He had appointed those who lived before. He will make the religion that He has chosen for them to stand supreme. He will replace their fear with peace and security so that they will worship God alone and consider no one equal to Him. Whoever becomes an unbeliever after this will be a sinful person. 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 [And] think not that those who are bent on denying the truth can elude [their final reckoning even if they remain unscathed] on earth: the fire is their goal [in the life to come] - and vile indeed is such a journey's end! 57
