Al-Adab Al-Mufrad, Hadith 1314 ⓘ
Abu Bakra reported that the Prophet, may Allah bless him and grant him peace, said, "Modesty is part of belief. Belief is in the Garden. Foul language is part of coarseness and coarseness is in the Fire."
حَدَّثَنَا سَعِيدُ بْنُ سُلَيْمَانَ، قَالَ: حَدَّثَنَا هُشَيْمٌ، عَنْ مَنْصُورٍ، عَنِ الْحَسَنِ، عَنْ أَبِي بَكْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ: الْحَيَاءُ مِنَ الإِيمَانِ، وَالإِيمَانُ فِي الْجَنَّةِ، وَالْبَذَاءُ مِنَ الْجَفَاءِ، وَالْجَفَاءُ فِي النَّارِ.
