Abu Hurairah reported the Prophet(ﷺ) as saying Abraham(peace be upon him) never told a lie except on three occasions twice for the sake of Allaah. Allaah quoted his words (in the Qur’an) “I am indeed sick” and “Nay, this was done by - this is their biggest one”. Once he was passing through the land of a tyrant (king). He stayed there in a place. People went to the tyrant and informed him saying “A man has come down here; he has a most beautiful woman with him.” So he sent for him (Abraham) and asked about her. He said she is my sister. When he returned to her, he said “he asked me about you and I informed him that you were my sister. Today there is no believer except me and you. You are my sister in the Book of Allaah (i.e., sister in faith). So do not belie me before him. The narrator then narrated the rest of the tradition. Abu Dawud said “A similar tradition has also been narrated by Shu’aib bin Abi Hamza from Abi Al Zinad from Al A’raj on the authority of Abu Hurairah from the Prophet (ﷺ).

Allah's Messenger (ﷺ) said, "Abraham did not tell a lie except on three occasions."

The Prophet (ﷺ) said: Abraham did not tell lies except three. (One of them was) when Abraham passed by a tyrant and (his wife) Sara was accompanying him (Abu Huraira then mentioned the whole narration and said:) (The tyrant) gave her Hajar. Sara said, "Allah saved me from the hands of the Kafir (i.e. infidel) and gave me Hajar to serve me." (Abu Huraira added:) That (Hajar) is your mother, O Banu Ma'-As-Sama' (i.e., the Arabs).

The Prophet (ﷺ) said, "The Prophet (ﷺ) Abraham emigrated with Sarah and entered a village where there was a king or a tyrant. (The king) was told that Abraham had entered (the village) accompanied by a woman who was one of the most charming women. So, the king sent for Abraham and asked, 'O Abraham! Who is this lady accompanying you?' Abraham replied, 'She is my sister (i.e. in religion).' Then Abraham returned to her and said, 'Do not contradict my statement, for I have informed them that you are my sister. By Allah, there are no true believers on this land except you and 1.' Then Abraham sent her to the king. When the king got to her, she got up and performed ablution, prayed and said, 'O Allah! If I have believed in You and Your Apostle, and have saved my private parts from everybody except my husband, then please do not let this pagan overpower me.' On that the king fell in a mood of agitation and started moving his legs. Seeing the condition of the king, Sarah said, 'O Allah! If he should die, the people will say that I have killed him.' The king regained his power, and proceeded towards her but she got up again and performed ablution, prayed and said, 'O Allah! If I have believed in You and Your Apostle and have kept my private parts safe from all except my husband, then please do not let this pagan overpower me.' The king again fell in a mood of agitation and started moving his legs. On seeing that state of the king, Sarah said, 'O Allah! If he should die, the people will say that I have killed him.' The king got either two or three attacks, and after recovering from the last attack he said, 'By Allah! You have sent a satan to me. Take her to Abraham and give her Ajar.' So she came back to Abraham and said, 'Allah humiliated the pagan and gave us a slave-girl for service."

Prophet Ibrahim (peace be upon him) never told a lie but only thrice: two times for the sake of Allah (for example, his words): "I am sick," and his words: "But it was the big one amongst them which has done that" and because of Sara (his wife). He had come in a land inhabited by haughty and cruel men along with Sara. She was very good-looking amongst the people, so he said to her: If these people were to know that you are my wife they would snatch you away from me, so if they ask you tell them that you are my sister and in fact you are my sister in Islam, and I do not know of any other Muslim in this land besides I and you. And when they entered that land the tyrants came to see her and said to him (the king): 'There comes to your land a woman, whom you alone deserve to possess', so he (the king) sent someone (towards her) and she was brought to him, and Ibrahim (peace be upon him) stood in prayer. When she visited him (the tyrant king came) he could help but stretch his hand towards her and his hand was tied up. He said: 'Supplicate to Allah so that He may release my hand and I will do no harm to you.' She did that and the man repeated (the same highhandedness) and his hand was again tied up more tightly than on the first occasion. He said the same thing to her again, and she again did that (supplicated), but he repeated (the same highhandedness and his hands were tied up more tightly than on the previous occasion). He then again said: 'Supplicate your Lord so that He may set my hand free; by Allah I shall do no harm to you.' She did and his hand was freed. Then he called the person who had brought her and said to him: 'You have brought to me the satan and you have not brought to me a human being, so turn them out from my land,' and he gave Hajar as a gift to her. She returned (along with Hajar) and when Ibrahim (peace be upon him) saw her, he said: 'How have you returned?' She said: 'With full safety (have I returned). Allah held the hand of that debauch and he gave me a maid-servant.' Abu Huraira said: 'O sons of the rain of the sky, she is your mother.'
