Al-Isthihada [bleeding (from the womb) in between a woman‘s periods]

Narrated 'Aisha:

Fatima bint Abi Hubaish said to Allah's Apostle, "O Allah's Apostle! I do not become clean (from bleeding). Shall I give up my prayers?" Allah's Apostle 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."

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 ﷺ يَا رَسُولَ اللَّهِ إِنِّي لاَ أَطْهُرُ، أَفَأَدَعُ الصَّلاَةَ فَقَالَ رَسُولُ اللَّهِ ﷺ " إِنَّمَا ذَلِكِ عِرْقٌ وَلَيْسَ بِالْحَيْضَةِ، فَإِذَا أَقْبَلَتِ الْحَيْضَةُ فَاتْرُكِي الصَّلاَةَ، فَإِذَا ذَهَبَ قَدْرُهَا فَاغْسِلِي عَنْكِ الدَّمَ وَصَلِّي ".
