It is narrated from Sayyiduna Abu Sa'id (may Allah be pleased with him) or Sayyiduna Abu Hurairah (may Allah be pleased with him) that when the Battle of Tabuk took place, the people were afflicted with severe hunger. They submitted: O Messenger of Allah! If you permit, we will slaughter our camels to arrange for food and fat. The Messenger of Allah (peace and blessings be upon him) said to them: Alright. But Sayyiduna Umar (may Allah be pleased with him) came and submitted: O Messenger of Allah! If the people slaughter their camels, the mounts will become few. Command them to bring their surplus food and drink, and you pray for blessing in it for them; it is hoped that Allah will bless it. So the Messenger of Allah (peace and blessings be upon him) had a leather dining cloth brought and spread it out, then called the Companions and said: Bring your surplus food. Someone brought a handful of corn, someone brought a handful of dates, and someone brought leftover pieces of bread, until some items were gathered on the dining cloth. Then the Prophet (peace and blessings be upon him) prayed for blessing upon those things and said: Now put this food into your vessels (and bags, etc.). So the Companions began to fill their vessels with this food, until they filled every vessel they found in the entire army, and they ate to their fill, but still much was left over. Seeing this scene, the Messenger of Allah (peace and blessings be upon him) said: I bear witness that there is no god but Allah and I am the Messenger of Allah. Whoever bears witness to these two things with a sincere heart, when he meets Allah, he will not be prevented from entering Paradise.
