Explanation & Benefits
Maulana Ataullah Sajid
Benefits and Issues: ➊ Every Muslim should be a well-wisher for another Muslim.
➋ If there is any defect in a transaction, it should be disclosed; it is possible that for the purpose for which the buyer wants to purchase, that defect may not be significant.
➌ One should not demand the price of a superior item for something inferior.
➍ Disclosing defects is a part of honesty, and honesty is an important quality of a Muslim.
