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 whosoever obeyeth Allah and His apostle, and dreadeth Allah and feareth Him - these! they are the achievers. 52 ۞ And they swear by Allah their strongest oaths that if you ordered them, they would go forth [in Allah 's cause]. Say, "Do not swear. [Such] obedience is known. Indeed, Allah is Acquainted with that which 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 And establish prayer and give zakah and obey the Messenger - that you may receive 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
