Ibn ‘Umar reported God’s messenger as saying, “When you meet one who has performed the pilgrimage, greet him, shake hands with him and tell him to ask forgiveness for you before he enters his house, for he has been forgiven.”
Abu Huraira reported God’s messenger as saying, “If anyone goes out to perform hajj or 'umra, or to fight with infidels, and dies on the way, God will record for him the reward of him who fights with infidels, him who performs the hajj and him who performs the 'umra.”
Abu Huraira reported the Prophet as saying, “Those who perform the hajj and those who perform the 'umra are people who have come to visit God. If they supplicate Him He will respond to them, and if they ask Him for forgiveness He will forgive them.”
