3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Faddal who has said the following:

“I heard a man asking abu al-Hassan, al-Rida , saying, ‘I prepare (special kind of flour) and sell it but people say that it should not be done.’ Al-Rida , said to him, ‘What is wrong with it? There is no offense in selling things in which a servant maintains piety before Allah.’”
