It is narrated from Sayyiduna Abu Umamah al-Bahili (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The handholds of Islam will be undone one by one; every time a handhold is undone, the people will cling to the one that follows it. The first of them to be undone will be governance (the Islamic system of rule), and the last of them the prayer."
