Abū al-Naḍr al-ʿAjlī reported: Abū ʿAbd Allāh said of a man who transports wine, swine, or carrion for a Christian that he regards eating the wage earned thereby as reprehensible, yet he still rules that the porter is entitled to his fee. If the employer is a Muslim, the censure is even more severe.

To sum up the discussion:

• Concerning the sale of one’s house to an unbeliever, we have already noted that Ahmad prohibited it.

• His disciples then differed: is this merely a matter of avoidance (tanziyh) or outright prohibition?

– Al-Sharīf Abū ʿAlī ibn Abī Mūsā said, “Ahmad disliked a Muslim’s selling his house to a dhimmī who will blaspheme against God in it and indulge in the forbidden. Should the Muslim proceed, he has behaved badly, yet the sale itself is not invalid.”

– Abū al-Ḥasan al-Āmidī likewise confined himself to describing it as disliked.

– Al-Khallāl, his associate, and the Qāḍī, however, their wording implies that it is unlawful, and we have already cited their statements.

The Qāḍī added: “It is not permissible to lease one’s house to someone who will turn it into a fire-temple, a church, or a place to sell wine—whether selling wine is stipulated in the contract or not, so long as he knows that wine will indeed be sold there.”
