Jābir (may Allah be pleased with him) reported that while the Muslims were digging a trench around Madīnah to prevent the enemies from attacking them, they found a hard boulder that they could not break with their axes. They informed the Messenger of Allah (may Allah's peace and blessings be upon him) about the situation. He himself went down the trench, with a stone tied to his stomach out of severe hunger. He took the axe and stroke the boulder once and it turned into sand. Jābir went to his house and asked his wife if they had some food. He related to her in what state of hunger the Messenger of Allah (may Allah's peace and blessings be upon him) was. She pulled out a bag of barely and they slaughtered a little goat which they had. She ground the barely and put the meat in a stony pot. Jābir then went and secretly told the Messenger of Allah (may Allah's peace and blessings be upon him) that he had made some food that would not be enough for everybody, and he invited the Prophet to come with some of his Companions. The Messenger of Allah (may Allah's peace and blessings be upon him) however, called out everybody who was working on the trench to come and eat. Afterwards, the Messenger of Allah (may Allah's peace and blessings be upon him) went to Jābir's house and asked for the dough, which he spat in, as well as in the pot of meat, and he supplicated Allah to bless that food. This is one of his exclusive features. He asked them to bring another baker to help Jābir's wife in making the food. Everybody (who was working) came and ate (to their fill) and then left. Surprisingly, the food that they had remained as if it had not been touched.
