What is the ruling regarding a person who performs Salah without having taken the obligatory ghusl?
If a person has already prayed and later realizes that he was in a state requiring ghusl, what should he do?
Al-ḥamdu lillāh, waṣ-ṣalātu wa-s-salāmu ʿalā Rasūlillāh, ammā baʿd!
If someone has performed Salah and afterwards comes to know that he was in a state of janābah (major ritual impurity) or any other condition requiring ghusl, then it is obligatory upon him to:
❀ Perform ghusl immediately to attain ritual purity.
❀ Repeat all the prayers he performed in that state.
The Messenger of Allah ﷺ said:
"لَا یَقْبَلُ اللّٰہُ صَلَاةً بِغَیْرِ طُہُورٍ"
(Ṣaḥīḥ Muslim, Kitāb aṭ-Ṭahārah, ḥadīth: 224; Sunan an-Nasā’ī, Kitāb aṭ-Ṭahārah, ḥadīth: 139)
Translation:
"Allah does not accept any prayer without purification."
Any Salah performed without the required ghusl is invalid until ghusl is performed and the Salah is repeated.
ھذا ما عندي والله أعلم بالصواب
