Abu Umamah reported: The Prophet, peace and blessings be upon him, said, “Modesty and reticence are two branches of faith. Profanity and temerity are two branches of hypocrisy.”
Al-Tirmidhi said, “Reticence is to speak little. Profanity is to speak obscenely. Temerity is to speak too often, such as those preachers who preach at great length and with eloquence, to be praised by people in what is not pleasing to Allah.”

عَنْ أَبِي أُمَامَةَ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ الْحَيَاءُ وَالْعِيُّ شُعْبَتَانِ مِنْ الْإِيمَانِ وَالْبَذَاءُ وَالْبَيَانُ شُعْبَتَانِ مِنْ النِّفَاقِ
قال الترمذي وَالْعِيُّ قِلَّةُ الْكَلَامِ وَالْبَذَاءُ هُوَ الْفُحْشُ فِي الْكَلَامِ وَالْبَيَانُ هُوَ كَثْرَةُ الْكَلَامِ مِثْلُ هَؤُلَاءِ الْخُطَبَاءِ الَّذِينَ يَخْطُبُونَ فَيُوَسِّعُونَ فِي الْكَلَامِ وَيَتَفَصَّحُونَ فِيهِ مِنْ مَدْحِ النَّاسِ فِيمَا لَا يُرْضِي اللَّهَ
