We hear and we obey.

أَفِي قُلُوبِهِم مَّرَضٌ أَمِ ارْتَابُوا أَمْ يَخَافُونَ أَن يَحِيفَ اللَّهُ عَلَيْهِمْ وَرَسُولُهُ ۚ بَلْ أُولَٰئِكَ هُمُ الظَّالِمُونَ

إِنَّمَا كَانَ قَوْلَ الْمُؤْمِنِينَ إِذَا دُعُوا إِلَى اللَّهِ وَرَسُولِهِ لِيَحْكُمَ بَيْنَهُمْ أَن يَقُولُوا سَمِعْنَا وَأَطَعْنَا ۚ وَأُولَٰئِكَ هُمُ الْمُفْلِحُونَ

وَمَن يُطِعِ اللَّهَ وَرَسُولَهُ وَيَخْشَ اللَّهَ وَيَتَّقْهِ فَأُولَٰئِكَ هُمُ الْفَائِزُونَ

۞ وَأَقْسَمُوا بِاللَّهِ جَهْدَ أَيْمَانِهِمْ لَئِنْ أَمَرْتَهُمْ لَيَخْرُجُنَّ ۖ قُل لَّا تُقْسِمُوا ۖ طَاعَةٌ مَّعْرُوفَةٌ ۚ إِنَّ اللَّهَ خَبِيرٌ بِمَا تَعْمَلُونَ

قُلْ أَطِيعُوا اللَّهَ وَأَطِيعُوا الرَّسُولَ ۖ فَإِن تَوَلَّوْا فَإِنَّمَا عَلَيْهِ مَا حُمِّلَ وَعَلَيْكُم مَّا حُمِّلْتُمْ ۖ وَإِن تُطِيعُوهُ تَهْتَدُوا ۚ وَمَا عَلَى الرَّسُولِ إِلَّا الْبَلَاغُ الْمُبِينُ

Is there a disease in their hearts? Or do they doubt or fear lest Allah and His Messenger (sallAllaahu 'alayhi wa sallam) should wrong them in judgement. Nay, it is they themselves who are the Zalimun (polytheists, hypocrites and wrong-doers, etc.).

The only saying of the faithful believers, when they are called to Allah (His Words, the Qur'an) and His Messenger (sallAllaahu 'alayhi wa sallam), to judge between them, is that they say: "We hear and we obey." And such are the prosperous ones (who will live forever in Paradise).

And whosoever obeys Allah and His Messenger (sallAllaahu 'alayhi wa sallam), fears Allah, and keeps his duty (to Him), such are the successful ones.

They swear by Allah their strongest oaths, that if only you would order them, they would leave (their homes for fighting in Allah's Cause). Say: "Swear you not; (this) obedience (of yours) is known (to be false). Verily, Allah knows well what you do."

Say: "Obey Allah and obey the Messenger, but if you turn away, he (Messenger Muhammad ) is only responsible for the duty placed on him (i.e. to convey Allah's Message) and you for that placed on you. If you obey him, you shall be on the right guidance. The Messenger's duty is only to convey (the message) in a clear way (i.e. to preach in a plain way)."
