What did the Prophet Muhammad (peace be upon him) do when he covered a distance of three miles or three farsakh according to Anas b. Malik?
 Yahya b. Yazid al-Huna'i reported:                      I asked Anas b. Malik about shortening of prayer. He said: When the Messenger of' Allah (may peace be upon him) had covered a distance of three miles or three farsakh (Shu'ba, one of the narrators, had some doubt about it) he observed two rak'ahs.
