Muhammad ibn Ahmad ibn Yahya from Ya‘qub ibn Yazid from Ibrahim ibn Abd al-Hamid from Jamil from Muhammad ibn Muslim from Abu Ja’far عليه السلام, peace be upon him, he said: Imam al-Baqir عليه السلام said: “The Friday prayer is obligatory upon whoever is within two farsakhs of it. And the meaning of that is when there is a just Imam.” And Imam عليه السلام said: “If there is a distance of three miles between the two congregational prayers, then there is no harm in these ones holding the congregational prayer and those ones holding it as well. And there should not be less than three miles between the two congregational prayers.”
