It is narrated from Sayyiduna Ghaziyyah bin al-Harith (may Allah be pleased with him) that he heard the Prophet (peace and blessings be upon him) say: "There is no emigration (hijrah) after the Conquest (of Makkah); now only three things remain: jihad, intention, and gathering (in the way of Allah)."
