Muwatta Malik 1145

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ أَبِي الزُّبَيْرِ الْمَكِّيِّ، أَنَّ رَجُلاً، خَطَبَ إِلَى رَجُلٍ أُخْتَهُ فَذَكَرَ أَنَّهَا قَدْ كَانَتْ أَحْدَثَتْ فَبَلَغَ ذَلِكَ عُمَرَ بْنَ الْخَطَّابِ فَضَرَبَهُ - أَوْ كَادَ يَضْرِبُهُ - ثُمَّ قَالَ مَا لَكَ وَلِلْخَبَرِ

Yahya related to me from Malik from Abu'z-Zubayr al-Makki that somebody asked a man for his sister in marriage and the man mentioned that she had committed fornication. Umar ibn al-Khattab heard about it and he beat the man or almost beat him, and said, "What did you mean by giving him such information?
