Abu Hurairah reported,

The Messenger of Allah ﷺ went out one day, or one night, and there he came upon Abu Bakr and Umar. He asked, "What has brought you out of your homes at this hour?"They replied, "Hunger, Messenger of Allah."He said, "By the One in whose hand is my soul, the same thing that brought you out has brought me out as well. Get up."They rose with him and came to the home of one of the Ansar, but he was not there. When his wife saw the Messenger of Allah ﷺ, she said, "Welcome."The Messenger of Allah ﷺ asked her, "Where is so-and-so?"She replied, "He has gone to fetch us some fresh water."Just then the Ansari man arrived, and when he looked at the Messenger of Allah ﷺ and his two companions, he said, "Praise be to Allah, no one today has more honored guests than I do."He went off and brought them a cluster of dates containing unripe, dried, and fresh dates, and said, "Eat from these." Then he took up the knife to slaughter for them.The Messenger of Allah ﷺ said to him, "Avoid the milk-producing one."So he slaughtered for them, and they ate from the sheep and from that cluster of dates, and they drank. When they had eaten and drunk their fill, the Messenger of Allah ﷺ said to Abu Bakr and Umar, "By the One in whose hand is my soul, you will surely be questioned about these blessings on the Day of Resurrection. Hunger drove you from your homes, and you did not return until these blessings reached you."In another narration, "Do not slaughter one that gives milk."

عن أبي هريرة قال

خرج رسول الله ﷺ ذات يوم أو ليلة فإذا هو بأبي بكر وعمر، فقال: ما أخرجكما من بيوتكما هذه الساعة؟ قالا: الجوع يا رسول الله. قال: وأنا والذي نفسي بيده لأخرجني الذي أخرجكما قوموا. فقاموا معه، فأتى رجلا من الأنصار، فإذا هو ليس في بيته، فلما رأته المرأة قالت: مرحبا وأهلا. فقال لها رسول الله ﷺ: أين فلان؟ قالت: ذهب يستعذب لنا من الماء، إذ جاء الأنصاري فنظر إلى رسول الله ﷺ وصاحبيه، ثم قال: الحمد لله ما أحد اليوم أكرم أضيافا مني، قال: فانطلق، فجاءهم بعذق فيه بسرا وتمر ورطب. فقال: كلوا من هذه، وأخذ المدية، فقال له رسول الله ﷺ: إياك والحلوب. فذبح لهم فأكلوا من الشاة، ومن ذلك العذق وشربوا، فلما أن شبعوا ورووا قال رسول الله ﷺ لأبي بكر وعمر: والذي نفسي بيده لتسألن عن هذا النعيم يوم القيامة، أخرجكم من بيوتكم الجوع، ثم لم ترجعوا حتى أصابكم هذا النعيم. وفي رواية: لا تذبحن ذات در.
