What is the ruling on fasting for one who becomes in a state of major ritual impurity?
Machine translationRead the Arabic original
The questioner : The questioner says: I was in a state of major ritual impurity, and I made the intention to fast, and I was hesitating as to whether my fast was valid or not?
The Shaykh : If a person wakes up in a state of major ritual impurity and wants to fast, there is no harm in his fasting, and he has done nothing wrong. The Messenger (peace and blessings be upon him) used to wake up in a state of major ritual impurity from intercourse with his wives, and he would fast (peace and blessings be upon him). We have in the Messenger a good example. However, it is obligatory for a person to perform ghusl (the full ritual bath) before he prays Fajr, because he does not pray before he performs ghusl.
