Salama reported,

The people's provisions ran low and they became destitute, so they came to the Prophet ﷺ seeking permission to slaughter their camels, and he granted them permission.Umar met them and they told him what had happened. He said, "How will you survive after losing your camels?"Umar then went in to the Prophet ﷺ and said, "Messenger of Allah, how will they survive after losing their camels?"The Messenger of Allah ﷺ said, "Call out to the people to bring whatever provisions they have left."A leather sheet was spread out, and they placed their remaining provisions on it. The Messenger of Allah ﷺ then supplicated and asked Allah to bless it. After that, he called them with their containers, and the people scooped from it until they had filled them all.Then the Messenger of Allah ﷺ said, "I bear witness that there is no god but Allah, and that I am the Messenger of Allah."

حدثنا بشر بن مرحوم حدثنا حاتم بن إسماعيل عن يزيد بن أبي عبيد

عن سلمة رضي الله عنه قال

خفت أزواد الناس وأملقوا فأتوا النبي ﷺ في نحر إبلهم فأذن لهم فلقيهم عمر فأخبروه فقال ما بقاؤكم بعد إبلكم فدخل عمر على النبي ﷺ فقال يا رسول الله ما بقاؤهم بعد إبلهم قال رسول الله ﷺ ناد في الناس يأتون بفضل أزوادهم فدعا وبرك عليه ثم دعاهم بأوعيتهم فاحتثى الناس حتى فرغوا ثم قال رسول الله ﷺ أشهد أن لا إله إلا الله وأني رسول الله
