That the Messenger of Allah (ﷺ) said: "What I fear most from my Ummah is the behavior of the people of Lut."
Jami` at-Tirmidhi Book 17, Hadith 41
← Previous Hadith That the Messenger of Allah (ﷺ) said: "Whomever you find doing the actions of the people of Lut then kill the one doing it, and the one it is done to."

Jami` at-Tirmidhi Book 17, Hadith 40 Next Hadith → That 'Ali burnt some people who apostasized from Islam. This news reached Ibn 'Abbas, so he said: "If it were me I would have killed them according to the statement of Messenger of Allah (ﷺ). The Messenger of Allah (ﷺ) said: 'Whoever changes his religion then kill him.' And I would not have burned them because the Messenger of Allah (ﷺ) said: 'Do not punish with the punishment of Allah.' So this reached 'Ali, and he said: "Ibn 'Abbas has told the truth."
