Sayyiduna al-Harith bin Wahb (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) said: "My Ummah will remain upon Islam as long as they do not delay the Maghrib prayer until the stars become intertwined, in imitation of the Jews, and as long as they do not hasten the Fajr prayer, in imitation of the Christians, and as long as they do not leave the responsibility of funerals to the deceased's family."
