It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Madinah is the centre and stronghold of Islam, the home of faith, the land of emigration, and the place where the lawful and the unlawful were revealed and settled."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from the Prophet (peace and blessings be upon him) only with this chain; Qalun is alone in narrating it."
