"That is a vein, so when your period comes, do not pray, and when your period is over, purify yourself and pray in between one period and the next." Abu 'Abdur-Rahman said: Hisham bin 'Urwah reported this Hadith from 'Urwah, and he did not mention what Al-Mundhir mentioned in it.
أَنَّهَا أَتَتْ رَسُولَ اللَّهِ ﷺ فَشَكَتْ إِلَيْهِ الدَّمَ فَقَالَ لَهَا رَسُولُ اللَّهِ ﷺ إِنَّمَا ذَلِكِ عِرْقٌ فَانْظُرِي إِذَا أَتَاكِ قَرْؤُكِ فَلاَ تُصَلِّي وَإِذَا مَرَّ قَرْؤُكِ فَلْتَطَهَّرِي ثُمَّ صَلِّي مَا بَيْنَ الْقُرْءِ إِلَى الْقُرْءِ قَالَ أَبُو عَبْدِ الرَّحْمَنِ قَدْ رَوَى هَذَا الْحَدِيثَ هِشَامُ بْنُ عُرْوَةَ عَنْ عُرْوَةَ وَلَمْ يَذْكُرْ فِيهِ مَا ذَكَرَ الْمُنْذِرُ
