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 He who obeyeth Allah and His messenger, and feareth Allah, and keepeth duty (unto Him): such indeed are the victorious. 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 Allah and obey the Apostle; but if you turn back, then on him rests that which is imposed on him and on you rests that which is imposed on you; and if you obey him, you are on the right way; and nothing rests on the Apostle but clear delivering (of the message). 54 God has promised those of you who have attained to faith and do righteous deeds that, of a certainty, He will cause them to accede to power on earth, even as He caused [some of] those who lived before them to accede to it; and that, of a certainty, He will firmly establish for them the religion which He has been pleased to bestow on them; and that, of a certainty, He will cause their erstwhile state of fear to be replaced by a sense of security [seeing that] they worship Me [alone,] not ascribing divine powers to aught beside Me. But all who, after [having understood] this, choose to deny the truth - it is they, they who are truly iniquitous! 55 Establish worship and pay the poor-due and obey the messenger, that haply ye may find 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
