"Do not marry those whom your fathers married from among women, except what has already passed," meaning: what occurred before the prohibition. "Indeed, it was a shameful act and an object of hatred"—a detestation from God—"and an evil way," meaning: an evil path.
﴿وَلا تَنْكِحُوا مَا نَكَحَ آبَاؤُكُمْ مِنَ النِّسَاءِ إِلا مَا قَدْ سلف﴾ يَعْنِي: مَا قد مُضِيّ قبل التَّحْرِيم ﴿إِنَّهُ كَانَ فَاحِشَةً وَمَقْتًا﴾ بغضا من الله ﴿وَسَاءَ سَبِيلا﴾ أَي: بئس المسلك.
