[Machine] I used to walk behind my father and he would tell me to go to dirty places and clean places. So I entered upon Umm Salamah and asked her about that. She said, "I heard the Messenger of Allah ﷺ say, 'Whatever comes after it purifies it.'"
كُنْتُ أَجُرُّ ذَيْلِي فَأَمُرُّ بِالْمَكَانِ الْقَذِرِ وَالْمَكَانِ الطَّيِّبِ فَدَخَلْتُ عَلَى أُمِّ سَلَمَةَ فَسَأَلْتُهَا عَنْ ذَلِكَ فَقَالَتْ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ يُطَهِّرُهُ مَا بَعْدَهُ
