" تَجْلِسُ أَيَّامَ أَقْرَائِهَا ثُمَّ تَغْتَسِلُ وَتُؤَخِّرُ الظُّهْرَ وَتُعَجِّلُ الْعَصْرَ وَتَغْتَسِلُ وَتُصَلِّي وَتُؤَخِّرُ الْمَغْرِبَ وَتُعَجِّلُ الْعِشَاءَ وَتَغْتَسِلُ وَتُصَلِّيهِمَا جَمِيعًا وَتَغْتَسِلُ لِلْفَجْرِ "
It was narrated that Zainab bint Jahsh said: "I said to the Prophet (ﷺ) that I was suffering from Istihadah. He said: 'Do not pray during the days of your period, then perform Ghusl and delay Zuhr and bring Maghrib and bring 'Isha' forward and pray them together, and perform Ghusl for Fajr."
