Musannaf Ibn Abi Shaybah 29440 — A man who collides with another man

Isma'il bin Salim said that Imam al-Sha'bi was asked about two boats that collided, and one of them sank. He answered: There is no liability upon those of the other boat. But any man who moors a boat on the route of the Muslims, and it then causes harm, will be liable.
