ومن باع بثمن حال ثم أجله أجلا معلوما مؤجلا
Translation: If the seller later grants a known deferment for an immediate price, that price becomes deferred.
An immediately payable price is due at once. If the seller subsequently grants a known period of deferment, Quduri treats the price as payable at the resulting agreed time.
Example: Rs 60,000 was due immediately, but the seller grants a clear 30-day extension. The term needs to be identified; vague arrangements such as “whenever convenient” are not equivalent to a specified payment date.
