The Noble Prophet (peace and blessings be upon him) said: "A man kept following us; when you invited us, he was not present. Now, if you permit him, he may come inside." This hadith is narrated from Sayyiduna Abu Mas'ud Badri and Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both). These are the words of Abu Mas'ud Badri's narration. (The complete narration is as follows): It is narrated from Sayyiduna Abu Mas'ud Badri (may Allah be pleased with him) that a man, who was called Abu Shu'aib, came to his butcher slave and ordered him to prepare food for five people, because he had perceived from the face of the Messenger of Allah (peace and blessings be upon him) that he was hungry. He prepared the food, then he invited the Noble Prophet (peace and blessings be upon him) and his companions. When the Noble Prophet (peace and blessings be upon him) stood up, a man started following him, who was not present at the time the invitation was given. When the Messenger of Allah (peace and blessings be upon him) reached the door of the (host's) house, he said to the householder: ... " He said: I permit him, let him come inside."
