Excellent manner of conduct in the Quran
This is in the Quran 25: 63-74
وَعِبَادُ الرَّحْمَنِ الَّذِينَ يَمْشُونَ عَلَى الْأَرْضِ هَوْنًا وَإِذَا خَاطَبَهُمُ الْجَاهِلُونَ قَالُوا سَلَامًا
وَالَّذِينَ يَبِيتُونَ لِرَبِّهِمْ سُجَّدًا وَقِيَامًا
وَالَّذِينَ يَقُولُونَ رَبَّنَا اصْرِفْ عَنَّا عَذَابَ جَهَنَّمَ إِنَّ عَذَابَهَا كَانَ غَرَامًا
إِنَّهَا سَاءتْ مُسْتَقَرًّا وَمُقَامًا
وَالَّذِينَ إِذَا أَنفَقُوا لَمْ يُسْرِفُوا وَلَمْ يَقْتُرُوا وَكَانَ بَيْنَ ذَلِكَ قَوَامًا
وَالَّذِينَ لَا يَدْعُونَ مَعَ اللَّهِ إِلَهًا آخَرَ وَلَا يَقْتُلُونَ النَّفْسَ الَّتِي حَرَّمَ اللَّهُ إِلَّا بِالْحَقِّ وَلَا يَزْنُونَ وَمَن يَفْعَلْ ذَلِكَ يَلْقَ أَثَامًا
يُضَاعَفْ لَهُ الْعَذَابُ يَوْمَ الْقِيَامَةِ وَيَخْلُدْ فِيهِ مُهَانًا
إِلَّا مَن تَابَ وَآمَنَ وَعَمِلَ عَمَلًا صَالِحًا فَأُوْلَئِكَ يُبَدِّلُ اللَّهُ سَيِّئَاتِهِمْ حَسَنَاتٍ وَكَانَ اللَّهُ غَفُورًا رَّحِيمًا
وَمَن تَابَ وَعَمِلَ صَالِحًا فَإِنَّهُ يَتُوبُ إِلَى اللَّهِ مَتَابًا
وَالَّذِينَ لَا يَشْهَدُونَ الزُّورَ وَإِذَا مَرُّوا بِاللَّغْوِ مَرُّوا كِرَامًا
وَالَّذِينَ إِذَا ذُكِّرُوا بِآيَاتِ رَبِّهِمْ لَمْ يَخِرُّوا عَلَيْهَا صُمًّا وَعُمْيَانًا
وَالَّذِينَ يَقُولُونَ رَبَّنَا هَبْ لَنَا مِنْ أَزْوَاجِنَا وَذُرِّيَّاتِنَا قُرَّةَ أَعْيُنٍ وَاجْعَلْنَا لِلْمُتَّقِينَ إِمَامًا
أُوْلَئِكَ يُجْزَوْنَ الْغُرْفَةَ بِمَا صَبَرُوا وَيُلَقَّوْنَ فِيهَا تَحِيَّةً وَسَلَامًا
خَالِدِينَ فِيهَا حَسُنَتْ مُسْتَقَرًّا وَمُقَامًا
The explanation:
(The [faithful] servants of [God] Most Gracious are those who walk upon the earth modestly, and when the ignorant address them answer: "Peace [to you.]"
Who pass the night [obedient] prostrate to their Lord and standing.
Who say: "Our Lord, avert from us the doom of Hell; surely its doom is an extreme loss."
Evil, indeed, will it be [as] a settlement and [as] an abode.
And those who when they spend are neither extravagant nor miserly, but they make their livelihood between these [two extremes.]
And those who call not upon another god, along with God;
and kill not the [living] person that God has prohibited [its killing] save for the right [cause]; and do not commit fornication: for he who does that shall meet with a penalty for his sins.
Doubled shall be the chastisement for him on the Judgment Day, and he shall abide therein humbled.
Unless he repents, believes and works righteous deeds, for God will change the evil [habits] of such [persons] into good, and God is Most Forgiving, Most Merciful.
And whoever repents and works righteous [deeds, should] turn to God with a permanent repentance.
And those who witness not falsehood; and when they pass by futility, they only pass by honorably.
And those who, when they are reminded of the revelations of their Lord [when they are about to commit a sin], they fall not deaf and blind thereat.
And those who say: "Our Lord, grant us from our wives [sons] and [from] our seed [grandsons] that which may cause contentment of our eyes, and make us models to those who ward off [sins.]
These will be rewarded with a most beautiful building [in Paradise] because they endured patiently, and they will meet therein with greeting [of the angels] and the word of "Peace" to each other.
Abiding therein for ever. Happy indeed will it be [as] a settlement and [as] an abode.
