Hadith.3861 - Aban narrated from Isma'il bin Al-Fadl who said: I asked Abu Abdillah (as) about selling pasture when it is irrigated by flowing water, where a man directs his water to the land, irrigates the grass, and he is the one who dug the canal and owns the water, planting with it whatever he wishes. Imam (as) said: "If the water is his, then he may plant with it whatever he wishes and sell it for whatever he likes."

Hadith.3862 - Sama'ah asked him about purchasing fodder crops, where a man buys them but does not harvest them, and then decides to leave them until they produce spikes of barley or wheat. He had bought them from their roots, and any tax due on them was the responsibility of the cultivator. Imam (as) said: "If he stipulated at the time of purchase that he may either cut them as fodder or leave them as they are until they produce spikes, then there is no harm. Otherwise, it is not proper for him to leave them until they produce spikes."
