“This is concerning my question before abu ‘Abd Allah (a.s.), about a man’s selling pastures which needs watering. He works to provide water for its grass and he is the one who has dug the well and canal and he has water for the plantation of whatever he likes to cultivate. He (the Imam) said, ‘If water belongs to him he can cultivate whatever he likes and sell to whoever he likes.’ I then asked him (the Imam) about selling the remaining portions of wheat or barley stems after harvest. He (the Imam) said, ‘It is lawful, thus, he can sell if he wants.’”
