"I heard the Messenger of Allah ﷺ say: 'The affairs of the Children of Israel remained fair until Muwalladun emerged among them - the children of female slaves from other nations. They spoke of their own opinions (in religious matters) and so they went astray and led others astray.'"
سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ لَمْ يَزَلْ أَمْرُ بَنِي إِسْرَائِيلَ مُعْتَدِلاً حَتَّى نَشَأَ فِيهِمُ الْمُوَلَّدُونَ أَبْنَاءُ سَبَايَا الأُمَمِ فَقَالُوا بِالرَّأْىِ فَضَلُّوا وَأَضَلُّوا
[Machine] "The matter of the Children of Israel remains moderate, without any issue, until women from other nations gave birth to children from men of the Children of Israel. They then started offering their opinions, leading them astray."
«مَا زَالَ أَمْرُ بَنِي إِسْرَائِيلَ مُعْتَدِلًا لَيْسَ فِيهِ شَيْءٌ حَتَّى نَشَأَ فِيهِمُ الْمُوَلَّدُونَ أَبْنَاءُ سَبَايَا الْأُمَمِ أَبْنَاءُ النِّسَاءِ الَّتِي سَبَتْ بَنُو إِسْرَائِيلَ مِنْ غَيْرِهِمْ فَقَالُوا فِيهِمْ بِالرَّأْيِ فَأَضَلُّوهُمْ»
"لَمْ يَزَلْ أَمْرُ بَنِي إِسْرَائِيلَ مُعْتَدلًا حَتَّى نَشَأَ فيهِم المُوَلَّدُونَ وَأَبْنَاءُ سَبَايا الأُممِ الَّتِي كَانَتْ بَنُو إِسْرَائِيلَ تَسْبِيهَا، فَقَالُوا بِالرأْى فَضَلُّوا وَأَضَلُّوا".
