The only saying of the believers when they were called to Allah and His apostle that he might judge between them was that they said: we hear and we obey. And these! they are the very ones blissful. 51 and only those attain true success who obey Allah and His Messenger and fear Allah and refrain from His disobedience. 52 ۞ Now [as for those half-hearted ones,] they do swear by God with their most solemn oaths that if thou [O Apostle] shouldst ever bid them to do so, they would most certainly go forth [and sacrifice themselves]. Say: "Swear not! Reasonable compliance [with God's message is all that is required of you]. Verily, God is aware of all that 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 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 Attend to your prayers and pay the zakat and obey the Messenger, so that you may be shown 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
