Sahih al-Bukhari Book 67, Hadith 152
Some lady said, "O Allah's Messenger (ﷺ)! My husband has another wife, so it is sinful of me to claim that
he has given me what he has not given me (in order to tease her)?" Allah's Messenger (ﷺ) said, The one who
pretends that he has been given what he has not been given, is just like the (false) one who wears two
garments of falsehood."
that `Umar entered upon Hafsa and said, "O my daughter! Do not be misled by the manners of her who is proud of her beauty because of the love of Allah's Messenger (ﷺ) for her." By 'her' he meant `Aisha. `Umar added, "Then I told that to Allah's Messenger (ﷺ) and he smiled (on hearing that).
The Prophet, said, "There is none having a greater sense of Ghira than Allah. And for that He has forbidden the doing of evil actions (illegal sexual intercourse etc.) There is none who likes to be praised more than Allah does."
