‘Abdallah b. Busr told of a man saying, “Messenger of God, the ordinances of Islam are too many for me, so tell me something to which I may cling.” He replied, “Your tongue will continue to be supple by making mention of God.” Tirmidhi and Ibn Majah transmitted it. Tirmidhi saying this is a <i>hasan gharib</i> tradition.
