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 ‘Asr forward and pray; then delay Maghrib and bring ‘Isha’ forward and pray them together, and perform Ghusl for Fajr.” (Sahih)
