She reported that the Prophet ﷺ used to stay with Zaynab bint Jahsh and drink honey at her home. So Hafsa and I agreed that whichever of us the Prophet ﷺ entered upon should say to him, "I detect on you the smell of maghafir."He entered upon one of them and she said this to him.He replied, "Rather, I drank honey at Zaynab bint Jahsh's, and I will never do it again."Then was revealed, "Why do you prohibit what Allah has made lawful for you, seeking..." up to "If you both repent to Allah..." [Tahrim 66:1–4], referring to Ayesha and Hafsa, and "And when the Prophet confided to one of his wives a statement..." refers to his saying ﷺ, "Rather, I drank honey."
حدثنا أحمد بن محمد بن حنبل حدثنا حجاج بن محمد قال قال ابن جريج عن عطاء أنه سمع عبيد بن عمير قال سمعت
تخبر أن النبي ﷺ كان يمكث عند زينب بنت جحش فيشرب عندها عسلا فتواصيت أنا وحفصة أيتنا ما دخل عليها النبي ﷺ فلتقل إني أجد منك ريح مغافير فدخل على إحداهن فقالت له ذلك فقال بل شربت عسلا عند زينب بنت جحش ولن أعود له فنزلت {لم تحرم ما أحل الله لك تبتغي} إلى {إن تتوبا إلى الله} لعائشة وحفصة رضي الله عنهما {وإذ أسر النبي إلى بعض أزواجه حديثا} لقوله ﷺ بل شربت عسلا
