Say prayers before engaging in intimate activities such as sexual relations with your spouse.

This hadith speaks to the power of prayer and its ability to protect us from harm. It was narrated by Ibn 'Abbas, who was a companion of Prophet Muhammad, peace be upon him. In this hadith, Prophet Muhammad is teaching us that if we say a prayer before engaging in sexual relations with our spouse, then it will protect any child that may be born as a result from any harm caused by Satan. This teaches us the importance of saying prayers and invoking Allah's protection before doing anything important or intimate in our lives. It also shows us how powerful Allah's protection can be when we ask for it sincerely and with faith.
