1. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hammad from al-Halabiy who has said the following: “I once asked abu ’Abd Allah (a.s.), about a traveler if he can perform Salah (prayer) behind a non-traveler. He (the Imam) said, ‘After performing two Rak‘at, he then can move away whenever he wants.’”
