وَعَنْ أَبِي أُمَامَةَ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «الْحَيَاءُ وَالْعِيُّ شُعْبَتَانِ مِنَ الْإِيمَانِ وَالْبَذَاءُ وَالْبَيَانُ شُعْبَتَانِ مِنَ النِّفَاقِ» . رَوَاهُ التِّرْمِذِيّ
Abu Umamah (may Allah be pleased with him) narrates from the Prophet (peace and blessings of Allah be upon him), he said: "Modesty and speaking little are branches of faith, while obscene speech and exaggeration are two branches of hypocrisy." Its chain is authentic, narrated by al-Tirmidhi.
