Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Suhaim bin Nofal that he said: Hazrat Abdullah bin Masood instructed me, "What will be your condition when those who pray will fight among themselves?" I asked, "Will this happen?" He replied, "Yes, it will be the companions of Muhammad (peace be upon him)." The narrator said, "I asked, 'What should I do at that time?'" He replied, "Restrain your tongue, keep your place of residence hidden, and it is obligatory upon you to do good, and do not abandon good because of evil."
