she heard the Messenger of Allah say: "Do not kill your children secretly, for by the One in Whose Hand is my soul, intercourse with a breastfeeding woman catches up with people when they are riding their horses (in battle) and wrestles them to the ground." (Using translation from Ibn Mājah 2012)
أَنَّهَا سَمِعَتْ رَسُولَ اللهِ ﷺ يَقُولُ «لَا تَقْتُلُنَّ أَوْلَادَكُنَّ سِرًّا فَوَالَّذِي نَفْسِي بِيَدِهِ إِنَّ الْغِيلَ لَيُدْرِكُ الْفَارِسَ عَلَى ظَهْرِ فَرَسِهِ حَتَّى يَصْرَعُهُ»
