Sayyiduna Ghaziyyah bin al-Harith (may Allah be pleased with him) related that some young men of Quraysh wanted to emigrate to the Messenger of Allah (peace and blessings be upon him), but their fathers prevented them. They mentioned this to the Messenger of Allah (peace and blessings be upon him), and the Messenger of Allah (peace and blessings be upon him) said: "There is no emigration after the Conquest (of Makkah); now only jihad and intention remain."
