Sunan Abi Dawud
حَدَّثَنَا الرَّبِيعُ بْنُ نَافِعٍ أَبُو تَوْبَةَ، حَدَّثَنَا مُحَمَّدُ بْنُ مُهَاجِرٍ، عَنْ أَبِيهِ، عَنْ أَسْمَاءَ بِنْتِ يَزِيدَ بْنِ السَّكَنِ، قَالَتْ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " لاَ تَقْتُلُوا أَوْلاَدَكُمْ سِرًّا فَإِنَّ الْغَيْلَ يُدْرِكُ الْفَارِسَ فَيُدَعْثِرُهُ عَنْ فَرَسِهِ " .
Narrated Asma', daughter of Yazid ibn as-Sakan,: I heard the Messenger of Allah (ﷺ) as saying: Do not kill your children secretly, for the milk, with which a child is suckled while his mother is pregnant, overtakes the horseman and throws him from his horse.
