Ruling on taking the lead in prayer in the home of one who lets his garment hang below the ankles

Question:
Honorable Shaykh, may Allah grant you success. If you are better at recitation than the owner of the house, and more knowledgeable in jurisprudence as well, and the owner of the house is one who commits a major sin openly, such as letting his garment hang below the ankles or shaving his beard, does he become the imam for you?

Answer:
If there is no obstacle, you may take the lead. Or you say to him, “Let me pray,” meaning you ask his permission? There is nothing wrong with that. But as for taking the lead over him without his permission and without asking him, that is not fitting, because this may turn him away, because this act may turn him away and increase him in evil.
