Sayyiduna Yazid bin Al-Aswad (may Allah be pleased with him) says: I performed Hajj with the Messenger of Allah (peace and blessings be upon him), and offered the morning prayer in Mina. When the prayer was finished, he saw that two men were sitting at the back; they had not prayed with the congregation. The Prophet (peace and blessings be upon him) said: "Bring them to me." When they were brought, the flesh under their arms was trembling. The Prophet (peace and blessings be upon him) asked: "Did you not pray with us?" They said: O Messenger of Allah! We had already prayed at home because we thought we might miss the prayer. The Prophet (peace and blessings be upon him) said: "Do not do this in the future. When you have prayed at home and then find the congregation, then pray with them; it will be counted as a voluntary prayer for you." One of them said: O Messenger of Allah! Pray for forgiveness for us. So the Prophet (peace and blessings be upon him) prayed for their forgiveness. People gathered around the Prophet (peace and blessings be upon him) like a flock of sheep. At that time, I was a young and strong man, so I made my way through the crowd and went to the Prophet (peace and blessings be upon him), took his hand and placed it on my chest. I have never seen a hand more excellent and cooler than the hand of the Prophet (peace and blessings be upon him).
