Once a traveler was passing through the city of Madina, he was intending to sell off his horse so as to have some money for further travels. It was quite early, the market was empty but he saw a buyer approaching him in the market. The buyer turned out to be our Prophet (saww). Deal was done and Prophet (saww) went to his home to fetch the money. Meanwhile, someone approached that traveler asking him for the price of his horse. The traveler said that he had already sold it to the Prophet (saww), the new buyer promised to pay more than what he has already sold it for. Since there weren’t many people around to witness the deal of the Prophet (saww), the traveler refused to acknowledge any deal with the Prophet (saww) upon Prophet’s arrival with the money.
Time was passing by and the market was getting started with more and more people joining in, many of whom started to take interest in what was happening with the horse deal. As it was decided, Prophet (saww) was asked to bring forth a witness or leave the deal. Since there was no one present at the time of the deal, Prophet (saww) had decided to leave the deal as such.
Suddenly, someone claimed that he had witness the deal taking place and favored the Prophet’s version of the events. Upon the completion of the deal, Prophet asked that witness, how was it that you claimed to be the witness despite you not being present at the scene and seeing it all? The witness replied, Ya Rasoolallah (saww), this was just a matter of a horse deal, you said that there is a God called Allah, when I trusted you over that I can trust you over this as well!
