Sayyiduna Ibn Abbas (may Allah be pleased with them both) said regarding Allah Almighty’s statement: «لَاتُخْرِجُوهُنَّمِنبُيُوتِهِنَّوَلَايَخْرُجْنَإِلَّاأَنيَأْتِينَبِفَاحِشَةٍمُّبَيِّنَةٍ» “Do not drive them out of their houses, nor should they leave, unless they commit a clear indecency.” In its explanation, he said: «وَالْفَاحِشَةٍمُّبَيِّنَةٍ» This means that she becomes a cause of disgrace for her family, so when she does this, it becomes lawful for them to expel her.
