various corruptions will arise in my community, so strike with sword the one who tries to cause separation in the matter of Muslims when they are united, whoever he be.
Sunan Abi Dawud Book 42, Hadith 167
← Previous Hadith He who disapproves is guiltless, and he who disapproves is safe. Qatadah said : it means one who feels its disapproval in his heart, and one who expresses disapproval in his heart.

Sunan Abi Dawud Book 42, Hadith 166 Next Hadith → ‘Ali mentioned about the people of al Nahrawan, saying: Among them there will be a man with a defective hand or with a small hand. if you were not to overjoy. I would inform you of what Allah has promised (the reward for) those who will kill them at the tongue of Muhammad (May peace be upon him). I asked : Have you heard this from him? He replied : Yes, by the lord of the Ka’bah.
