The Prophet said: "The five daily prayers, from one Friday to the next, and fulfilling the trust are all expiation for whatever (sins) come between them." I said: "What is fulfilling the trust?" He said: Having a bath to cleanse oneself from sexual impurity, for under every hair there is the state of sexual impurity."
أَنَّ النَّبِيَّ ﷺ قَالَ الصَّلَوَاتُ الْخَمْسُ وَالْجُمُعَةُ إِلَى الْجُمُعَةِ وَأَدَاءُ الأَمَانَةِ كَفَّارَةٌ لِمَا بَيْنَهَا قُلْتُ وَمَا أَدَاءُ الأَمَانَةِ قَالَ غُسْلُ الْجَنَابَةِ فَإِنَّ تَحْتَ كُلِّ شَعَرَةٍ جَنَابَةً
