Is it permissible to bear witness under oath in court concerning a husband beating his wife, given that the questioner did not witness the beating firsthand but is certain of it due to the wife's cries for help and her actions?

"The matter of testimony is grave, as it is a legal proof that establishes the truth, and it must be rendered accurately. It is impermissible for a Muslim to bear witness to something they did not see, due to the injustice and sin involved. If you are called to testify, do not bear witness that you saw a beating you did not witness, for merely hearing or an outcry is not sufficient to testify about a beating. Rather, testify only to what you saw and heard. Spouses should live together in kindness, and if not, then separation should be with grace. Beating one's wife unjustly is a great evil."
