My intention of writing the question was to actually make it accessible for people to get this information, nonetheless regarding Zahir, the statement was cherry picked, they were good friends and the prophet also began joking with him just like how the brother Jeschu said, and the entire story goes as follows,
Anas (ra) said, "There was a man from amongst the Bedouins whose name was Zahir bin Haram. Whenever he came to Medinah for a need, he brought something for the Prophet (SAWS) as a gift, like cottage cheese or butter. Likewise, when the Prophet (SAWS) would prepare something to give to him whenever wanted to leave, such as dates and so on. The Prophet (SAWS) used to love him and say, "Zahir is our Bedouin and we are his city dwellers." Zahir was not very good looking. One say, Zahir (ra) left the desert and came to Allah's Messenger (SAWS) but did not find him. He has some merchandise to sell so he went on to the market place. When the Prophet (SAWS) found out about his arrival, he went to the market place looking for him. When he arrived, he saw him selling his merchandise with sweat pouring down from his face. He wore Bedouin clothers which did not smell good either. The Prophet (SAWS) hugged him tightly from behind, while Zahir was unaware and could not see who it was. Zahir (ra) became scared and said, "Let me go! Who is this?!" But the Prophet (SAWS) remained silent. Zahir tried to release himself from his grip and started to look right and left. When he saw the Prophet (SAWS) he relaxed and calmed down, placing his back against the Prophet's chest. The Prophet (SAWS) began to joke with him, saying to the public: "W ho will buy this slave?! Who will buy this slave?" Thereupon, Zahir (ra) looked at himself and thought of his extreme poverty, for he had neither wealth or good looks. He said, "You will find me unmarketable, 0' Messenger of Allah." The Prophet (SAWS) said, "But you are not unmarketable with Allah (SWT). You are very precious to Allah." "How often we cry over Fate, but abundant good lies just behind it. 0' Soul, it is goodness, even if it arrives after a while."
