What is the ruling on paying a sum of money to someone to register my attendance in all theoretical lectures at the university, without the need for my personal presence?

The basic principle is that institutional regulations are established to safeguard the public interest, and it is not permissible for each individual to interpret them according to their personal circumstances, in order to prevent chaos. The questioner knows that bribery is a major sin, and a curse has been invoked against it. His statement that bribery harms no one is unfounded, for it does not achieve justice among students, involves lying and forgery, misplacing money, and aiding in its unlawful consumption.
