What is the ruling on false testimony?

Question:
The questioner says: I am an employee at one of the companies, and a serious disagreement occurred between me and the manager, in which I hit him because he was harassing us in our work, especially at prayer time, as he is not a Muslim. I took the case to the higher authorities, and they asked me to bring witnesses that I did not hit him, because I denied hitting him. I actually brought the witnesses, and they testified to that so that I could return to my job. I am now regretful of what I did. What should I do? Please guide us. May Allah bless you.

Answer:
This action is not permissible. This is false testimony. Allah (Exalted and Majestic is He) says: It was obligatory for you to admit the mistake and ask this man for forgiveness, even if he is a disbeliever, because you transgressed against him and wronged him. You transgressed against him and wronged him. This is not permissible for you, even if he is a disbeliever. It was obligatory for you to admit the truth, be patient with the ruling of the Shari'ah, or ask him for forgiveness. Yes.
