Sever all relations with him. Do not look at him, do not accept any service from him, do not speak to him, and do not let him sit in front of you. Make him sit to the right or left. Do not teach him his lesson separately, do not put right your appearance to please him, do not laugh and joke with him, and do not talk about him or praise him before anyone. If you are still unable to completely safeguard your eyes, stop teaching him. The fundamental point is that it is not appropriate for those who are inclined to boys to undertake the job of teaching. This is especially so when a person committed a sin even once with a boy, then it is not permissible for him to teach for the rest of his life. If not, he will fall into the sin again. It is better to serve as an imam [in a Masjid]. If one cannot do that, it is better for him to sell vegetables than to use teaching as an excuse to fall into the disobedience of Allah Ta’ala and thereby be disgraced in this world and in the Hereafter.
