Do not kill your children secretly

This hadith is about the wrongfulness of killing children secretly. It was narrated by Muhajir bin Abu Muslim, from Asma' bint Yazid bin Sakary who was his freed slave woman that she heard the Messenger of Allah say that one should not kill their children in secret as it is a great sin. He also said that intercourse with a breastfeeding woman catches up with people when they are riding their horses and wrestles them to the ground. This means that even if someone tries to hide their sins, Allah will still catch up with them and punish them for it eventually. Therefore, one should always strive to do good deeds and stay away from sins as much as possible so they can be rewarded in this life and the hereafter.
