Narrated Abu Huraira (may Allah be pleased with him): The Prophet (peace and blessings of Allah be upon him) said: "Ibrahim (peace be upon him) migrated along with (his wife) Sarah (may Allah be pleased with her), and they reached a town where there was a king, one of the kings or (he said) a tyrant, one of the tyrants. It was reported to him that Ibrahim (peace be upon him) had come with a very beautiful woman. So he sent a man to ask: 'O Ibrahim, who is this woman with you?' Ibrahim (peace be upon him) replied: 'She is my sister.' (The messenger said: The king is calling this woman.) After that, Ibrahim said to Sarah (peace be upon her): 'There is no believer on the face of the earth except you and me.' Then Ibrahim (peace be upon him) sent Sarah to the king. (When she reached the king,) the king turned his attention towards her, so she performed ablution and stood up to pray, and said: 'O Allah, if I believe in You and Your Messenger, and if I have protected my private parts from everyone except my husband, then do not let this disbeliever overpower me.' As soon as she made this supplication, the disbeliever fell down and began to rub his foot on the ground. Abu Huraira (may Allah be pleased with him) said that Sarah (peace be upon her), seeing this state, said: 'O Allah! If he dies, people will say that she killed the king.' Then his condition went away. He turned towards her again, but she got up, performed ablution, and started praying, and said: 'O Allah! If I believe in You and Your Messenger, and I have protected my private parts from everyone except my husband, then do not let this disbeliever overpower me.' (After this) the king again fainted, to the extent that if he died, people would say that she killed the king. Then again his condition subsided. Then the second or third time, he said to the people: 'You have brought me a human or a devil? Take her back to Ibrahim (peace be upon him) and also hand over Ajar (Hajar) to her.' So she returned to Ibrahim (peace be upon him) and said: 'Do you know that Allah has humiliated that disbeliever and has also sent a slave-girl (Hajar, peace be upon her) for service.'"
