Fight them! Allah will chastise them at your hands, and He will lay them low and give you victory over them, and He will heal the breasts of folk who are believers.

Knowledge
Chapter: (The superiority of) comprehending knowledge
Narrated Ibn `Umar:
We were with the Prophet (ﷺ) and fresh dates of a palm tree were brought to him. On that he said, "Amongst the trees, there is a tree which resembles a Muslim." I wanted to say that it was the datepalm tree but as I was the youngest of all (of them) I kept quiet. And then the Prophet (ﷺ) said, "It is the date-palm tree."
