Narrated Ibn `Abbas:
The Prophet (ﷺ) said, "When (a person) an adulterer commits illegal sexual intercourse then he is not a believer at the time he is
doing it; and when somebody steals, then he is not a believer at the time he is stealing."
حَدَّثَنِي عَمْرُو بْنُ عَلِيٍّ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ دَاوُدَ، حَدَّثَنَا فُضَيْلُ بْنُ غَزْوَانَ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " لاَ يَزْنِي الزَّانِي حِينَ يَزْنِي وَهْوَ مُؤْمِنٌ، وَلاَ يَسْرِقُ حِينَ يَسْرِقُ وَهْوَ
مُؤْمِنٌ ".

Abu Huraira reported Allah's Messenger (may peace be upon him) as saying: Avoid suspicion, for suspicion is the gravest lie in talk and
do not be inquisitive about one another and do not spy upon one another and do not feel envy with the other, and nurse no malice, and nurse no aversion and hostility against one another. And be fellow-brothers and servants of Allah.
