This is narrated from Amr bin Dinar (may Allah have mercy on him).
And Imam al-Shafi'i (may Allah have mercy on him) said: "It is also narrated from Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him) that he sold a garden of his, then its buyer was struck by a calamity (on the fruit), and he took the price from him; and I do not know whether this (report) is established or not."
