عَنْ عَبْدِ اللَّهِ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ((إِنَّ الْمُؤْمِنَ لَيْسَ بِاللَّعَّانِ وَلَا الطَّعَّانِ وَلَا الْفَاحِشِ وَلَا الْبَذِيِّ))
It is narrated from Sayyiduna Abdullah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: A believer is neither one who taunts, nor one who curses, nor one who uses obscene language, nor one who is foul-mouthed.
