It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that once bread and meat were presented before the Prophet (peace and blessings be upon him). Then the Prophet (peace and blessings be upon him) asked for water for ablution, performed ablution, and offered the Zuhr prayer. Then the remaining food was brought and he ate it, and then stood for prayer without performing ablution again. Similarly, once I went to Sayyiduna Umar (may Allah be pleased with him), and on his dining mat there was a bowl in which there was bread and meat, and another bowl was placed there in which there was also bread and meat. Sayyiduna Umar (may Allah be pleased with him) ate from it, and stood for prayer without performing a new ablution.
