What is the ruling on one whose job is repairing radios and televisions?

The questioner : The day before yesterday, in the mosque of Taqwa during the Fajr prayer, a man in the mosque introduced me to him. He said to me with affection, "I want to introduce you to the professor, a young man with a beard and a thobe and a hat, may Allah will it." He said, "I want to introduce you to the brother with affection." I said to him, "We have a young man in the mosque who gives us a word in the morning and we benefit from him, so come and listen to it." So he attended today to listen to you, he was pleased, and he said, "May Allah reward you with good." He was happy with you, but he had a specific question. I said to him, "Go ahead." He said to me, "I work as a professor. This young man’s job, the one who came to attend, is a professor at our Shaykh’s industrial college. This industrial college, he is a professor there for repairing radios and televisions. And they want to transfer him to another college, which is for the deaf and mute, so that the deaf and mute can repair televisions and radios, and he will teach them. So he says to me, 'Is there something wrong with my job? May Allah reward you with good.' I explained to him the explanation that you explain, meaning what we comprehend from you regarding cooperation in righteousness and piety and cooperation in sin and aggression. I mentioned to him that ten were cursed in the case of intoxicants, five were cursed in the case of riba, and three were cursed in the case of bribery. All this cursing is upon three people: the one who eats riba, the one who drinks intoxicants, and the one who gives the bribe. They participated in a matter concerning three. When he said, 'By Allah, my brother, we asked the scholars and they did not detail it for us like this,' I said to him, 'Our Shaykh details it for us, may Allah reward him with good.' I said to him, 'Can you estimate, for example, these people are cursed for the sake of three categories? So if we say it becomes cursed by the consequences of the three, it is five. If we say three thousand in the Muslim society are cursed, the ones cursed because of them are five thousand. Say five hundred thousand sinners, three million, the ones cursed are also five hundred thousand more, specific in enjoining the good and forbidding the evil.' He said to me, 'Allah is the Greatest, my brother, what is this job? By Allah, truly this.' I said to him, 'What do you think the television does? What does the radio do?' He said to me, 'Disasters.' I said to him, 'Well, the answer is with you. Why do you teach them to repair it... you teach them to...?' He said to me, 'If Allah wills, what am I supposed to do?' I said, 'This will come back to you. Fear Allah as much as you are able , leave this job, and Allah (Glorified and Exalted is He) will compensate you with something better than it .' He said to me, 'By Allah, may Allah reward you with good and may Allah bless you.' Meaning, as you say, my Shaykh, his perspective changed when he found this among the people who asked them, they asked them first, and you have no relation; you are teaching repair, what is this, and you are serving the disabled so that they can serve themselves.

The Shaykh : ... in short, and you get money. Allah is the Greatest.

The questioner : A young man, may Allah will it, a Shaykh, meaning.
