My father and Muhammad b. al-Hasan narrated to us. They said: Sa`d b. `Abdullah narrated to us from Musa b. al-Hasan and al-Hasan b. `Ali from Ahmad b. Hilal from Muhammad b. Abi `Umayr from Ja`far b. `Uthman from Sama`a b. Mehran. He said:

I said to Abi `Abdillah regarding Maghrib: We prayed, but we fear that the Sun was behind the mountain, and that the mountain had hid it from us. So, he said: You do not need to climb the mountain.
