The Holy Qur’an: At-Tawba (9:71)
وَالْمُؤْمِنُونَ وَالْمُؤْمِنَاتُ بَعْضُهُمْ أَوْلِيَاءُ بَعْضٍ ۚ يَأْمُرُونَ بِالْمَعْرُوفِ وَيَنْهَوْنَ عَنِ الْمُنْكَرِ وَيُقِيمُونَ الصَّلَاةَ وَيُؤْتُونَ الزَّكَاةَ وَيُطِيعُونَ اللَّهَ وَرَسُولَهُ ۚ أُولَٰئِكَ سَيَرْحَمُهُمُ اللَّهُ ۗ إِنَّ اللَّهَ عَزِيزٌ حَكِيمٌ
The Believers, men and women, are protectors one of another: they enjoin what is just, and forbid what is evil: they observe regular prayers, practise regular charity, and obey Allah and His Messenger. On them will Allah pour His mercy: for Allah is Exalted in power, Wise.
Narrated Abu Huraira:
Allah’s Apostle ﷺ said, “Beware of suspicion, for suspicion is the worst of false tales. and do not look for the others’ faults, and do not do spying on one another, and do not practice Najsh, and do not be jealous of one another and do not hate one another, and do not desert (stop talking to) one another. And O, Allah’s worshipers! Be brothers!”

Imaam al-Bukhaari (may Allaah have mercy on him) wrote a separate book on this issue which he called Juz’ fi Raf’ al-Yadayn (Section on Raising the Hands), in which he proved that the hands should be raised at these two points on the prayer, and he strongly denounced those who go against that. He narrated that al-Hasan said: “The Companions of the Messenger of Allaah (peace and blessings of Allaah be upon him) used to raise their hands during prayer when they bowed and when they stood up (from bowing).” Al-Bukhaari said, “Al-Hasan did not exclude any of the Sahaabah from that, and it was not proven that any one among the Sahaabah did not raise his hands.”

O you who have believed, avoid much [negative] assumption. Indeed, some assumption is sin. And do not spy or backbite each other. Would one of you like to eat the flesh of his brother when dead? You would detest it. And fear Allah ; indeed, Allah is Accepting of repentance and Merciful.
يَا أَيُّهَا الَّذِينَ آمَنُوا إِنَّمَا الْخَمْرُ وَالْمَيْسِرُ وَالْأَنْصَابُ وَالْأَزْلَامُ رِجْسٌ مِنْ عَمَلِ الشَّيْطَانِ فَاجْتَنِبُوهُ لَعَلَّكُمْ تُفْلِحُونَ
Ya ayyuha allatheena amanoo innama alkhamru waalmaysiru waalansabu waalazlamu rijsun min AAamali alshshaytani faijtaniboohu laAAallakum tuflihoona
O ye who believe! Intoxicants and gambling, (dedication of) stones, and (divination by) arrows, are an abomination,- of Satan’s handwork: eschew such (abomination), that ye may prosper.
Holy Qur’an: Al-Maaida (5:90)
آمِنُوا بِاللَّهِ وَرَسُولِهِ وَأَنْفِقُوا مِمَّا جَعَلَكُمْ مُسْتَخْلَفِينَ فِيهِ ۖ فَالَّذِينَ آمَنُوا مِنْكُمْ وَأَنْفَقُوا لَهُمْ أَجْرٌ كَبِيرٌ
Aminoo biAllahi warasoolihi waanfiqoo mimma jaAAalakum mustakhlafeena feehi faallatheena amanoo minkum waanfaqoo lahum ajrun kabeerun
Believe in Allah and His messenger, and spend (in charity) out of the (substance) whereof He has made you heirs. For, those of you who believe and spend (in charity),- for them is a great Reward.
۞ لَتُبْلَوُنَّ فِي أَمْوَالِكُمْ وَأَنْفُسِكُمْ وَلَتَسْمَعُنَّ مِنَ الَّذِينَ أُوتُوا الْكِتَابَ مِنْ قَبْلِكُمْ وَمِنَ الَّذِينَ أَشْرَكُوا أَذًى كَثِيرًا ۚ وَإِنْ تَصْبِرُوا وَتَتَّقُوا فَإِنَّ ذَٰلِكَ مِنْ عَزْمِ الْأُمُورِ
Ye shall certainly be tried and tested in your possessions and in your personal selves; and ye shall certainly Hear much that will grieve you, from those who received the Book before you and from those who worship many gods. But if ye persevere patiently, and guard against evil,-then that will be a determining factor in all affairs.
يَا أَيُّهَا الَّذِينَ آمَنُوا لَا يَسْخَرْ قَوْمٌ مِّن قَوْمٍ عَسَىٰ أَن يَكُونُوا خَيْرًا مِّنْهُمْ وَلَا نِسَاءٌ مِّن نِّسَاءٍ عَسَىٰ أَن يَكُنَّ خَيْرًا مِّنْهُنَّ ۖ وَلَا تَلْمِزُوا أَنفُسَكُمْ وَلَا تَنَابَزُوا بِالْأَلْقَابِ ۖ بِئْسَ الِاسْمُ الْفُسُوقُ بَعْدَ الْإِيمَانِ ۚ وَمَن لَّمْ يَتُبْ فَأُولَٰئِكَ هُمُ الظَّالِمُونَ – 49:11
O you who have believed, let not a people ridicule [another] people; perhaps they may be better than them; nor let women ridicule [other] women; perhaps they may be better than them. And do not insult one another and do not call each other by [offensive] nicknames. Wretched is the name of disobedience after [one’s] faith. And whoever does not repent – then it is those who are the wrongdoers. (Quran 49:11) Surah Al-Hujurat
