The slave-mother of Ibrahim ibn AbdurRahman ibn Awf asked Umm Salamah, the wife of the Prophet ﷺ: I am a woman having a long border of clothe and I walk in filthy place; (then what should I do?). Umm Salamah replied: The Messenger of Allah ( peace be upon him) said: What comes after it cleanses it.

أَنَّهَا سَأَلَتْ أُمَّ سَلَمَةَ زَوْجَ النَّبِيِّ ﷺ فَقَالَتْ إِنِّي امْرَأَةٌ أُطِيلُ ذَيْلِي وَأَمْشِي فِي الْمَكَانِ الْقَذِرِ فَقَالَتْ أُمُّ سَلَمَةَ قَالَ رَسُولُ اللَّهِ ﷺ يُطَهِّرُهُ مَا بَعْدَهُ

Yahya related to me from Malik from Muhammad ibn Umara from Muhammad ibn Ibrahim that the mother of the son of Ibrahim ibn Abd ar- Rahman ibn Awf questioned Umm Salama, the wife of the Prophet ﷺ and said, "I am a woman who wears a long skirt and (sometimes) I walk in dirty places." Umm Salama replied, "The Messenger of Allah ﷺ said, 'What follows (i.e. clean places) purifies it.' "

أَنَّهَا سَأَلَتْ أُمَّ سَلَمَةَ زَوْجَ النَّبِيِّ ﷺ فَقَالَتْ إِنِّي امْرَأَةٌ أُطِيلُ ذَيْلِي وَأَمْشِي فِي الْمَكَانِ الْقَذِرِ قَالَتْ أُمُّ سَلَمَةَ قَالَ رَسُولُ اللَّهِ ﷺ يُطَهِّرُهُ مَا بَعْدَهُ

[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
