Machine translationRead the Arabic original
The questioner:
Honorable Shaykh, may Allah grant you success. He says: Does the prohibition imply the invalidity of the prohibited act absolutely, or is there a distinction in this?
The Shaykh:
This is the rule: the prohibition implies invalidity. This is a principle of jurisprudence; the prohibition implies invalidity. So, if one prays in a forbidden garment, or in silk, or in a state of ritual impurity, his prayer is invalid, because this is prohibited. If one prays in a mosque that contains a grave, his prayer is invalid, because this is prohibited. It is prohibited to take graves as mosques. This is a great rule. Yes.
The questioner:
Honorable Shaykh, may Allah grant you success.
The Shaykh:
He prayed in a garment worth ten dirhams, one of which was forbidden, and his prayer is invalid, as in the hadith: Allah does not accept it. Yes.
