Kassera and mutawasseta you mean medium and high flow??.
The bath for light istehaza is one ghusl a day. So if you are fasting when should one take that ghusl. Especially when u are working and have a busy life, hiw can one make it easy for oneself

high flow and medium flow are kaseera and mutawasseta.
