Honest & Trustworthy Merchant

Whoever buys a sheep which has not been milked for a long time, has the option of returning it along with one Sa of dates; and the Prophet (ﷺ) forbade going to meet the seller on the way (as he has no knowledge of the market price and he may sell his goods at a low price).

Allah's Messenger (ﷺ) forbade Muzabana; and Muzabana means the selling of fresh dates (on the trees) for dried dates by measure and also the selling of fresh grapes for dried grapes by measure.

(When) Allah's Messenger (ﷺ) (wished to invoke curse or blessing on someone, he would do so at the end) of the recitation in the dawn prayer, when he had pronounced Allah-o-Akbar (for bending) and then lifted his head (saying):" Allah listened to him who praised Him; our Lord! to You is all praise" ; he would then stand up and say:" Rescue al-Walid b. Walid, Salama b. Hisham, and 'Ayyash b. Abd Rabi'a, and the helpless among the Muslims. O Allah! trample severely Mudar and cause them a famine (which broke out at the time) of Joseph. O Allah! curse Lihyan, Ri'l, Dhakwan, 'Usayya, for they disobeyed Allah and His Messenger." (The narrator then adds): The news reached us that he abandoned (this) when this verse was revealed:" You but no concern in the matter whether He turns to them (mercifully) or chastises them; surely they are wrongdoers" (ill. 127)

"The lawful is clear and the unlawful is clear, and between that are matters that are doubtful (not clear); many of the people do not know whether it is lawful or unlawful. So whoever leaves it to protect his religion and his honor, then he will be safe, and whoever falls into something from them, then he soon will have fallen into the unlawful. Just like if someone grazes (his animals) around a sanctuary, he would soon wind up in it. Indeed for every king is a sanctuary (pasture), and indeed Allah's sanctuary is what He made unlawful."

This Hadith is Hasan Sahih, it has been reported by more than one from Ash-Sha'bi, from An-Nu'man bin Bashir.
