The author Muhammad Salih Al-Munajjid at Islamqa.info in Fatwa # 3801 has stated the following:-
Al-Bukhaari reported in his Saheeh (no. 250) that ‘Aa’ishah said: “The Prophet (peace and blessings of Allaah be upon him)and I used to bathe from one vessel.”
Al-Haafiz said in al-Fath: “Al-Daawoodi interpreted this to mean that it is permissible for a man to look at his wife’s ‘awrah and vice-versa. This is supported by the report narrated by Ibn Hibbaan via Sulaymaan ibn Moosa, who was asked about a man looking at his wife’s private parts. He said: ‘I asked ‘Aa’ishah, and she referred to this hadeeth.’ This is evidence in this matter. And Allaah knows best.” [Source:- https://islamqa.info/en/answers/3801/husband-and-wife-taking-a-bath-together-and-looking-at-one-anothers-private-parts]
My main question is: where can I find Sulayman ibn Musa's narration in Sahih Ibn Hibban where he stated that Aisha (Radhi'allahu'anha) referred to the hadith in Bukhari when she was asked about whether a man could look at the private parts of her wife? Can someone please point out the narration in Sahih Ibn Hibban?
