باب اغْتِسَالِ الْحَائِضِ إِذَا وَجَبَ الْغُسْلُ عَلَيْهَا قَبْلَ أَنْ تَحِيضَ:Chapter: Ghusl for Menstruating Woman if Ghusl Became Obligatory Before Menstruation
Hadith 1188
حَدَّثَنَا سَعِيدُ بْنُ عَامِرٍ، عَنْ شُعْبَةَ، عَنْ مَنْصُورٍ، قَالَ: قَالَ إِبْرَاهِيمُ: "إِذَا بَلَّتْ أُصُولَهُ وَأَطْرَافَهُ، لَمْ تَنْقُضْهُ".
It is narrated from Mansur that Imam Ibrahim al-Nakha'i, may Allah have mercy on him, said: When the ends and roots of the hair get wet, she does not need to undo them.
