أَخْبَرَنَا أَسْوَدُ بْنُ عَامِرٍ ، حَدَّثَنَا شُعْبَةُ ، عَنْ عَمَّارٍ مَوْلَى بَنِي هَاشِمٍ، عَنْ ابْنِ عَبَّاسٍ رَضِيَ اللهُ عَنْهُ فِي الْمُسْتَحَاضَةِ :" تَدَعُ الصَّلَاةَ أَيَّامَ أَقْرَائِهَا، ثُمَّ تَغْتَسِلُ ثُمَّ تَحْتَشِي وَتَسْتَثْفِرُ، ثُمَّ تُصَلِّي "، فَقَالَ الرَّجُلُ : وَإِنْ كَانَ يَسِيلُ؟ قَالَ : " وَإِنْ كَانَ يَسِيلُ مِثْلَ هَذَا الْمَثْعَبِ "

Aswad bin Amir told us, Shu`bah told us, on the authority of Ammar, the client of Banu Hashim, on the authority of Ibn Abbas, may God be pleased with him, regarding Al-Mustadha: You should leave prayer for the days in which it is recited, then you should wash yourself, then wash yourself and ask yourself to cleanse yourself, then you should pray.” The man said: What if it was bleeding? He said: “Even if it flows like this stream.”
