(25) باب مَا يُكْرَهُ مِنَ الْمُثْلَةِ وَالْمَصْبُورَةِ وَالْمُجَثَّمَةِ
Narrated Ibn `Umar:
that he entered upon Yahya bin Sa`id while one of Yahya's sons was aiming at a hen after tying it. Ibn `Umar walked to it and untied it. Then he brought it and the boy and said. "Prevent your boys from tying the birds for the sake of killing them, as I have heard the Prophet (ﷺ) forbidding the killing of an animal or other living thing after tying them."
