Hassan bin Ziyaad (Rahmatullahi Alaihi) says: “Imaam Abu Haneefa (Rahmatullahi Alaihi) bought a consignment of fabric which had a defect in it. He sent the consignment to his partner to sell it off and instructed him to clearly inform the customers of the defect. It happened that the partner sold off the entire consignment but totally forgot to inform the customers. He also could not recall who the customers were. When Imaam Abu Haneefa (Rahmatullahi Alaihi ) learnt of this he was extremely disappointed. He then gave away all the money from that sale, the profits as well as the capital, as sadaqah. The total amount came to thirty thousand dirhams (which will presently be equivalent to several hundred thousand Rands). (Jawaahir Pare vol 2)

Hadhrat Abu Zar (Radhiallahu Anhu) reports that Nabi (Sallallahu Alaihi Wasallam) said: “Three types of people Allah Ta’ala will not speak to on the day of Qiyamah, nor will he look at them with the sight of mercy nor purify and cleanse them of their sins, and a severe punishment awaits them.” Hadrat Abu Zar (Radhiallahu Anhu) exclaimed: “Certainly such people are great losers and are doomed. O Rasulullah (Sallallahu Alaihi Wasallam), inform us who are these people?” Nabi (Sallallahu Alaihi Wasallam) replied: “The one who lets his garment flow beneath his ankles, the one who (after doing a favor to people), reminds them of his favors, and the one who takes false oaths when marketing and advertising his merchandise (i.e. he lies about the quality of the merchandise etc. to people with false oaths).

Hadhrat Abu Saeed (Radhiallahu Anhu) reports that Rasulullah (Sallallahu Alaihi Wasallam) said: The businessman who deals with honesty and trustworthiness will be in the company of the Ambiyaa, the siddeeqeen, and the shuhadaa (martyrs).

Hadhrat Hakeem ibn Hizaam (Radhiallahu Anhu) reports that Rasulullah (Sallallahu Alaihi Wasallam) said: “If the purchaser and seller deal with honesty and disclose the faults of the merchandise, Allah Ta’ala will grant them barkat (blessing) in their business transaction. However, if they transact with dishonesty, thereby concealing the faults of the merchandise and speaking lies to each other, the blessing of the transaction will be taken away.
