Narrated Abu Hurairah:
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).'" (DE)
