Prayer: If I Didn’t Observe the Proper Order in Ghusl for a Time, Are My Prayers and Fasts Valid?

English:

Question #527:

What is the ruling on the prayers and fasts of a person who for some time, due to ignorance of the ruling, did not observe the proper order in performing his ghusl?

Answer #527:

If he was performing his ghusl in a manner which is void according to Islamic law, he would be obligated to do qaḍā’ of all his prayers that he prayed without a valid ghusl. But regarding fasts, if he thought that his ghusl was correct, his fasts are ruled to be correct.
