Jabir bin Yazid bin Aswad narrates from his father (Sayyiduna Yazid, may Allah be pleased with him) that he performed the Fajr prayer with the Prophet Muhammad (peace and blessings be upon him). During the prayer of the Prophet (peace be upon him), two men remained seated in a corner and did not pray. Sayyiduna Yazid (may Allah be pleased with him) said: The Messenger of Allah (peace be upon him) called them, and they were brought while they were trembling. The Prophet (peace be upon him) said: "What prevented you from praying?" Both replied: "We had already prayed at our places." He said: "Do not sit like this in the future. When you have prayed at home and then find the Imam leading the prayer, then pray with the Imam, and that (prayer at home) will be counted as a voluntary prayer for you." Sayyiduna Yazid (may Allah be pleased with him) said: After that, people would get up, take hold of the hand of the Prophet (peace be upon him), and then wipe it over their faces. Sayyiduna Yazid (may Allah be pleased with him) said: I also took hold of the blessed hand of the Prophet (peace be upon him) and wiped it over my face, and it was colder than ice and more fragrant than musk.
