إذا رفع السكين إلى صبي فقتل به نفسه لا يضمن.
In the stated classical example, a person hands a knife to a child, and the child intentionally uses it against himself; the initial giver is not held liable through the stated ground of attribution.
This is not a statement that supplying a dangerous object is safe or acceptable. The example isolates the distinction between a facilitating act and a later, separately attributed act. Modern safeguarding duties and criminal or civil rules are different matters.
For this chapter, the analytical point is that making an instrument available and personally carrying out the harmful action are not identical legal roles.
