They set out with the Messenger of Allah ﷺ on a journey and made camp in groups, one group with so-and-so and another group with so-and-so. The narrator said, I camped with Abu Bakr's group, and with us was a Bedouin Arabi from the desert.We stopped at the dwelling of a Bedouin family among whom was a pregnant woman. The Arabi said to her, "Would it please you to give birth to a boy? If you give me a sheep, you will deliver a boy."So she gave him a sheep, and he chanted some rhymed incantations for her. He then slaughtered the sheep. When the people sat down to eat, a man said, "Do you know what this sheep is?" Then he told them.I saw Abu Bakr go off to relieve himself, sticking his finger down his throat to vomit it up.
أنهم خرجوا مع رسول الله ﷺ في سفر، فنزلوا رفقاء، رفقة مع فلان ورفقة مع فلان، قال: فنزلت في رفقة أبي بكر، فكان معنا أعرابي من أهل البادية، فنزلنا بأهل بيت من الأعراب، وفيهم امرأة حامل، فقال لها الأعرابي: أيسرك أن تلدي غلاما؟ إن أعطيتني شاة ولدت غلاما. فأعطته شاة، وسجع لها أساجيع، قال: فذبح الشاة، فلما جلس القوم يأكلون، قال رجل: أتدرون ما هذه الشاة؟ فأخبرهم قال: فرأيت أبا بكر متبرزا مستنبلا متقيئا.
Ahmad (11482) narrated it from Yahya bin Adam, who said, Zuhayr narrated to us, from Aswad bin Qays, from Nubayh (that is, Ibn Abdullah Anazi), from Abu Saeed Khudri, who mentioned it. Its isnad is sahih.
