وَأَصْحَٰبُ ٱلْأَيْكَةِ وَقَوْمُ تُبَّعٍۢ ۚ كُلٌّۭ كَذَّبَ ٱلرُّسُلَ فَحَقَّ وَعِيدِ
And the dwellers in the wood, and the folk of Tubb'a: every one denied their messengers, therefor My threat took effect.

Sahih al-Bukhari
Companions of the Prophet
Chapter: The merits of Al-Hasan and Al-Husain رضي الله عنهما
Narrated Ibn Abi Nu'm:
A person asked `Abdullah bin `Umar whether a Muslim could kill flies. I heard him saying (in reply). "The people of Iraq are asking about the killing of flies while they themselves murdered the son of the daughter of Allah's Messenger (ﷺ) . The Prophet (ﷺ) said, They (i.e. Hasan and Husain) are my two sweet basils in this world."
