The Devils Deception by Imam Ibn AL-Jawzi

Chapter Eleven: The Devil's Deception ef the $ijis
(;!i) said: "People of my nation will not be held accountable for the
thoughts of their minds (without acting upon it)."215
Then the man regretted his thought, and "regret is repentance"216
Iblis made him believe that full repentance required that he is to
kill himself. The Children of Israel were ordered to do so by Allah's
order: "So repent to your Creator and kill yourselves", whereas we have
been forbidden to do so by Allah's prohibition: "Do not kill yourselves. "
so he committed a major sin.
The Prophet (;!i) said: "Who kills himself by throwing himself
from a cliff will repeatedly do so in the hell fire for eternity."217
There have been cases in which a man, being separated from his
beloved, has put him to death.
I have been told that there was a $iji in a monastery in Baghdad
who had a boy living in the same house. The $iji man was condemned
for having a boy living with him. The $iji thereupon went
to the boy's room with a knife, killed him, and sat next to him crying.
The people of the monastery came and seeing this asked what
had happened, and the $iji confessed to the killing the boy. Being
brought before police he repeated the confession. The boy's father
came weeping and the $iji sat weeping also and said to the father:
'Why did you not make me his ransom.' The boy's father forgave
the killer. Later the $iji continued to visit the boy's grave.
