It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: Whoever recites this supplication before approaching his wife: Bismillah, Allahumma jannibni ash-shaytaan wa jannib ash-shaytaana ma razaqtana (In the name of Allah, O Allah! Keep me away from Satan and keep Satan away from what You grant us as offspring), then if a child is decreed for them from this union, Satan will never be able to harm that child.
