It is narrated from Sayyidah Subay'ah al-Aslamiyyah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever among you is able to die in Madinah, let him die there, for no one dies there except that I will be an intercessor or a witness for him on the Day of Resurrection."
