Narrated Abu Musa
Allah's Messenger (ﷺ) said. "My example and the example of the message with which Allah has sent me is like that of a man who came to some people and said, "I have seen with my own eyes the enemy forces, and I am a naked warner (to you) so save yourself, save yourself! A group of them obeyed him and went out at night, slowly and stealthily and were safe, while another group did not believe him and thus the army took them in the morning and destroyed them."
Narrated Abu Huraira
I heard Allah's Messenger (ﷺ) saying, "My example and the example of the people is that of a man who made a fire, and when it lighted what was around it, Moths and other insects started falling into the fire. The man tried (his best) to prevent them, (from falling in the fire) but they overpowered him and rushed into the fire. The Prophet (ﷺ) added: Now, similarly, I take hold of the knots at your waist (belts) to prevent you from falling into the Fire, but you insist on falling into it."
Narrated `Abdullah bin `Amr
The Prophet (ﷺ) said, "A Muslim is the one who avoids harming Muslims with his tongue or his hands. And a Muhajir (an emigrant) is the one who gives up (abandons) all what Allah has forbidden."
