أَبُو سُفْيَانَ طَلْحَةُ بْنُ نَافِعٍ، عَنْ أَبِي أَيُّوبَ
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." (Using translation from Ibn Mājah 598)
عَنْ أَبِي أَيُّوبَ الْأَنْصَارِيِّ ؓ قَالَ قَالَ رَسُولُ اللهِ ﷺ «الصَّلَوَاتُ الْخَمْسُ وَالْجُمُعَةُ إِلَى الْجُمُعَةِ وَأَدَاءُ الْأَمَانَةِ كَفَّارَةُ مَا بَيْنَهُمَا» قُلْتُ مَا أَدَاءُ الْأَمَانَةِ؟ قَالَ «غُسْلُ الْجَنَابَةِ فَإِنَّ تَحْتَ كُلِّ شَعْرَةٍ جَنَابَةٌ»
