Narrated `Aisha:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ ، قَالَ أَخْبَرَنَا مَالِكٌ ، عَنْ هِشَامِ بْنِ عُرْوَةَ ، عَنْ أَبِيهِ ، عَنْ عَائِشَةَ ، أَنَّهَا قَالَتْ قَالَتْ فَاطِمَةُ بِنْتُ أَبِي حُبَيْشٍ لِرَسُولِ اللَّهِ صلى الله عليه وسلم يَا رَسُولَ اللَّهِ إِنِّي لاَ أَطْهُرُ، أَفَأَدَعُ الصَّلاَةَ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِنَّمَا ذَلِكِ عِرْقٌ وَلَيْسَ بِالْحَيْضَةِ، فَإِذَا أَقْبَلَتِ الْحَيْضَةُ فَاتْرُكِي الصَّلاَةَ، فَإِذَا ذَهَبَ قَدْرُهَا فَاغْسِلِي عَنْكِ الدَّمَ وَصَلِّي " .
Fatima bint Abi Hubaish said to Allah's Messenger (ﷺ), "O Allah's Messenger (ﷺ)! I do not become clean (from bleeding). Shall I give up my prayers?" Allah's Messenger (ﷺ) replied: "No, because it is from a blood vessel and not the menses. So when the real menses begins give up your prayers and when it (the period) has finished wash the blood off your body (take a bath) and offer your prayers."
