Did the envious eye of the questioner cause the young man's death, and is what happened considered intentional murder?

Upon seeing the young man you admire, you should have said: "Masha'Allah, La Quwwata illa Billah (What Allah wills, there is no power except with Allah)" and prayed for blessings upon him, because the evil eye is real. So, whoever fears harming another should say that. It is not permissible for a Muslim to cause harm to his brother. The Prophet, peace and blessings be upon him, prevented those who had eaten garlic and onions from entering the mosque to prevent their harm. Some scholars even went as far as to prevent the person with the evil eye from mingling with people and confined them to their homes due to their severe harm, with the state covering their expenses if they were poor. All of this is to protect Muslims and prevent harm from society. Scholars differed on whether compensation is due from someone who destroys something with the evil eye. The preponderant opinion is that there is no qisas (retaliation), no diyah (blood money), and no kaffarah (expiation) for one who afflicts another with the evil eye. There is no expiation or guarantee upon you, but if you intentionally caused harm to your brother, then you are sinful, and you must repent and seek forgiveness. This is if the cause of death was the evil eye.
