16:120An-Nahl

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."

Abraham did not tell a lie except on three occasion. Twice for the Sake of Allah when he said, "I am sick," and he said, "(I have not done this but) the big idol has done it." The (third was) that while Abraham and Sarah (his wife) were going (on a journey) they passed by (the territory of) a tyrant. Someone said to the tyrant, "This man (i.e. Abraham) is accompanied by a very charming lady." So, he sent for Abraham and asked him about Sarah saying, "Who is this lady?" Abraham said, "She is my sister." Abraham went to Sarah and said, "O Sarah! There are no believers on the surface of the earth except you and I. This man asked me about you and I have told him that you are my sister, so don't contradict my statement." The tyrant then called Sarah and when she went to him, he tried to take hold of her with his hand, but (his hand got stiff and) he was confounded. He asked Sarah. "Pray to Allah for me, and I shall not harm you." So Sarah asked Allah to cure him and he got cured. He tried to take hold of her for the second time, but (his hand got as stiff as or stiffer than before and) was more confounded. He again requested Sarah, "Pray to Allah for me, and I will not harm you." Sarah asked Allah again and he became alright. He then called one of his guards (who had brought her) and said, "You have not brought me a human being but have brought me a devil." The tyrant then gave Hajar as a girl-servant to Sarah. Sarah came back (to Abraham) while he was praying. Abraham, gesturing with his hand, asked, "What has happened?" She replied, "Allah has spoiled the evil plot of the infidel (or immoral person) and gave me Hajar for service." (Abu Huraira then addressed his listeners saying, "That (Hajar) was your mother, O Bani Ma-is-Sama (i.e. the Arabs, the descendants of Ishmael, Hajar's son).

O, the best of creation; thereupon Allah's Messenger (ﷺ) said: He is Ibrahim (peace be upon him).

that the Messenger of Allah (ﷺ) said: "Ibrahim, peace be upon him, did not lie about anything at all - except for three: 'Verily I am sick (37:89)' while he was not sick. And his saying about Sarah: 'She is my sister' and his saying: 'Nay, this one, the biggest of them did it (21:63).'"
