Sahih Muslim Book 30, Hadith Number 5670.

Chapter : The extreme love of Allah’s Messenger (may peace be upon him) for his Umma, and his extreme anxiety to warn them against that which is a source of trouble to them.

Abu Huraira reported Allah’s Messenger (may peace be upon him) as saying: The similitude of mine and that of my Umma is that of a person who lit fire and there began to fall into it insects and moths. And I am there to hold you back, but you plunge into it.
