Read Ruku 72 of the Quran

مَّن يُطِعِ ٱلرَّسُولَ فَقَدْ أَطَاعَ ٱللَّهَ ۖ وَمَن تَوَلَّىٰ فَمَآ أَرْسَلْنَـٰكَ عَلَيْهِمْ حَفِيظًۭا ﴿٨٠﴾

He who obeys the Messenger has obeyed Allah; but those who turn away - We have not sent you over them as a guardian.

وَيَقُولُونَ طَاعَةٌۭ فَإِذَا بَرَزُوا۟ مِنْ عِندِكَ بَيَّتَ طَآئِفَةٌۭ مِّنْهُمْ غَيْرَ ٱلَّذِى تَقُولُ ۖ وَٱللَّهُ يَكْتُبُ مَا يُبَيِّتُونَ ۖ فَأَعْرِضْ عَنْهُمْ وَتَوَكَّلْ عَلَى ٱللَّهِ ۚ وَكَفَىٰ بِٱللَّهِ وَكِيلًا ﴿٨١﴾

And they say, "[We pledge] obedience." But when they leave you, a group of them spend the night determining to do other than what you say. But Allah records what they plan by night. So leave them alone and rely upon Allah. And sufficient is Allah as Disposer of affairs.

أَفَلَا يَتَدَبَّرُونَ ٱلْقُرْءَانَ ۚ وَلَوْ كَانَ مِنْ عِندِ غَيْرِ ٱللَّهِ لَوَجَدُوا۟ فِيهِ ٱخْتِلَـٰفًۭا كَثِيرًۭا ﴿٨٢﴾

Then do they not reflect upon the Qur'an? If it had been from [any] other than Allah, they would have found within it much contradiction.

وَإِذَا جَآءَهُمْ أَمْرٌۭ مِّنَ ٱلْأَمْنِ أَوِ ٱلْخَوْفِ أَذَاعُوا۟ بِهِۦ ۖ وَلَوْ رَدُّوهُ إِلَى ٱلرَّسُولِ وَإِلَىٰٓ أُو۟لِى ٱلْأَمْرِ مِنْهُمْ لَعَلِمَهُ ٱلَّذِينَ يَسْتَنۢبِطُونَهُۥ مِنْهُمْ ۗ وَلَوْلَا فَضْلُ ٱللَّهِ عَلَيْكُمْ وَرَحْمَتُهُۥ لَٱتَّبَعْتُمُ ٱلشَّيْطَـٰنَ إِلَّا قَلِيلًۭا ﴿٨٣﴾

And when there comes to them information about [public] security or fear, they spread it around. But if they had referred it back to the Messenger or to those of authority among them, then the ones who [can] draw correct conclusions from it would have known about it. And if not for the favor of Allah upon you and His mercy, you would have followed Satan, except for a few.

فَقَـٰتِلْ فِى سَبِيلِ ٱللَّهِ لَا تُكَلَّفُ إِلَّا نَفْسَكَ ۚ وَحَرِّضِ ٱلْمُؤْمِنِينَ ۖ عَسَى ٱللَّهُ أَن يَكُفَّ بَأْسَ ٱلَّذِينَ كَفَرُوا۟ ۚ وَٱللَّهُ أَشَدُّ بَأْسًۭا وَأَشَدُّ تَنكِيلًۭا ﴿٨٤﴾

So fight, [O Muhammad], in the cause of Allah; you are not held responsible except for yourself. And encourage the believers [to join you] that perhaps Allah will restrain the [military] might of those who disbelieve. And Allah is greater in might and stronger in [exemplary] punishment.

مَّن يَشْفَعْ شَفَـٰعَةً حَسَنَةًۭ يَكُن لَّهُۥ نَصِيبٌۭ مِّنْهَا ۖ وَمَن يَشْفَعْ شَفَـٰعَةًۭ سَيِّئَةًۭ يَكُن لَّهُۥ كِفْلٌۭ مِّنْهَا ۗ وَكَانَ ٱللَّهُ عَلَىٰ كُلِّ شَىْءٍۢ مُّقِيتًۭا ﴿٨٥﴾

Whoever intercedes for a good cause will have a reward therefrom; and whoever intercedes for an evil cause will have a burden therefrom. And ever is Allah, over all things, a Keeper.

وَإِذَا حُيِّيتُم بِتَحِيَّةٍۢ فَحَيُّوا۟ بِأَحْسَنَ مِنْهَآ أَوْ رُدُّوهَآ ۗ إِنَّ ٱللَّهَ كَانَ عَلَىٰ كُلِّ شَىْءٍ حَسِيبًا ﴿٨٦﴾

And when you are greeted with a greeting, greet [in return] with one better than it or [at least] return it [in a like manner]. Indeed, Allah is ever, over all things, an Accountant.

ٱللَّهُ لَآ إِلَـٰهَ إِلَّا هُوَ ۚ لَيَجْمَعَنَّكُمْ إِلَىٰ يَوْمِ ٱلْقِيَـٰمَةِ لَا رَيْبَ فِيهِ ۗ وَمَنْ أَصْدَقُ مِنَ ٱللَّهِ حَدِيثًۭا ﴿٨٧﴾

Allah - there is no deity except Him. He will surely assemble you for [account on] the Day of Resurrection, about which there is no doubt. And who is more truthful than Allah in statement.
