Yahya bin Yazid Hudnai reports: I asked Sayyiduna Anas bin Malik (may Allah be pleased with him) about the shortened prayer (Qasr Salah): He replied: Whenever the Prophet Muhammad (peace and blessings be upon him) set out on a journey of three miles (the narrator is in doubt, perhaps the words are:) three farsakh, he would perform two rak‘ahs. This doubt is from the narrator named Shu‘bah.
