Ali has narrated from his father from Hammad from Hariz from ibn Muslim who has said the following: “I once asked abu ‘Abd Allah (a.s.), about Friday. He (the Imam) said, ‘It (Friday Salah (prayer)) is obligatory up on those who live within two farsakh. If the distance is more than this then it is not obligatory on him.’” حسن - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (5/349))
