Musnad Ahmad 6406

Translation

✧ I witnessed Ibn Umar when a man from the people of Iraq asked him about a pilgrim in ihram who killed a fly. He said: O people of Iraq, you ask me about a pilgrim who killed a fly, while you have killed the son of the daughter of the Messenger of Allah ﷺ? The Messenger of Allah ﷺ said: They are my two sweet basils in this world.
