At the time of the battle of Tabūk, the people suffered famine, so they said: O Messenger of Allah, if you only permit us to slaughter our camels so we can eat their meat and use their fat. The Messenger of Allah (may Allah's peace and blessings be upon him) permitted them. Then ‘Umar (may Allah be pleased with him) came and said: O Messenger of Allah, if you do that, we will have a shortage in riding animals. Let them instead bring their leftover food, then invoke Allah's blessing on it, perhaps Allah will put some blessing in the small amount. The Messenger of Allah agreed and asked for a mat made of leather and spread it out. Then he asked them to bring their leftover food. One man brought a handful of corn; another brought a handful of dates; and another a piece of bread, until they collected an insignificant amount upon the mat. Then the Messenger of Allah invoked Allah's blessings and said: Take and fill your containers. So they filled their containers until all of the army members filled their containers. They ate to their fill and there was some food left over from it. The Messenger of Allah then said: I bear witness that there is no god but Allah, and that I am the Messenger of Allah. No slave will meet Allah believing in these two statements, free of doubt, and be prevented from Paradise, meaning that he must enter Paradise, either from the beginning with the survivors, or after being brought out of the Fire.
