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 whoever obeys the command of Allah and His Noble Messenger, and fears Allah, and practices piety – so it is they who are the successful. 52 ۞ They strongly swear by God that they would march to fight (for the cause of God) if you were to order them to. Tell them, "You do not need to swear; fighting for the cause of God is a virtuous deed and God is Well 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 Think not the unbelievers able to frustrate God in the earth; their refuge is the Fire -- an evil homecoming. 57
