قَالَ مَالِكٌ فِي الرَّجُلِ يُطَلِّقُ امْرَأَتَهُ، فَإِذَا مَضَتِ الثَّلَاثَةُ الْأَشْهُرِ، قَالَتِ الْمَرْأَةُ : أَنَا حَامِلٌ، قَالَ : إِنْ أَنْكَرَ زَوْجُهَا حَمْلَهَا، لَاعَنَهَا .
Imam Malik, may Allah have mercy on him, said: If a man divorces his wife, and after three months the woman says: "I am pregnant," and the husband denies her pregnancy, then li'an will be obligatory.
