أَخْبَرَنَا حَجَّاجٌ ، حَدَّثَنَا حَمَّادٌ ، عَنْ يُونُسَ ، عَنْ الْحَسَنِ ، قَالَ :" إِذَا رَأَتْ الدَّمَ فَإِنَّهَا تُمْسِكُ عَنْ الصَّلَاةِ، تَعُدُّ أَيَّامِ حَيْضِهَا يَوْمًا أَوْ يَوْمَيْنِ، ثُمَّ هِيَ بَعْدَ ذَلِكَ مُسْتَحَاضَةٌ "

Hajjaj told us, Hammad told us, on the authority of Yunus, on the authority of Al-Hasan, who said: “If she sees blood, she should abstain from praying and count the days of her menstruation.” A day or two, then after that she is mustahaadah.”
