It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Whoever recites these words three times in the evening: "I seek refuge in the perfect words of Allah from the evil of what He has created," no poisonous thing will harm him that night. Our family had learned this supplication and they used to recite it. Once, by chance, one of our girls was bitten by something, but she did not feel any pain at all.
