Obscenity and vulgarity are not part of Islam
I was in a gathering with the Prophet ﷺ and Abū Samurah was in front of me. Then the Messenger of Allah ﷺ said, "Verily, obscenity and vulgarity are not part of Islam. Verily, the best people in Islam are those with the best character."
كُنْتُ فِي مَجْلِسٍ فِيهِ النَّبِيُّ ﷺ قَالَ وَأَبِي سَمُرَةُ جَالِسٌ أَمَامِي فَقَالَ رَسُولُ اللهِ ﷺ: «إِنَّ الْفُحْشَ وَالتَّفَحُّشَ لَيْسَا مِنَ الْإِسْلَامِ، وَإِنَّ أَحْسَنَ النَّاسِ إِسْلَامًا أَحْسَنُهُمْ خُلُقًا.»
