—significantly above the usual level.
– al-siʿr (price): pronounced with a kasra beneath the sīn and sukun on the ʿayn; it is the figure against which goods are valued.
– siʿr lanā ("Set prices for us"): an imperative derived from tasʿīr; it denotes the Muslim ruler’s requiring people to buy and sell at a fixed, limited price, with no increase or decrease.
– al-Qābiḍ: the Withholder of provision, who constricts by His wisdom and justice.
– al-Bāsit: the Expander of provision, who enlarges it by His wisdom and bounty.
Names that form such contrasting pairs should not be ascribed to Allah in isolation; absolute perfection lies in combining both attributes together.
– bi-maẓlama: with fatḥa on the mīm and kasra on the lām; it means something taken unlawfully. With a fatḥa on the lām it becomes the verbal noun ẓulm (wrongdoing).

Points derived from the ḥadīth:
1 – The prices of foodstuffs in Madinah rose during the Prophet’s ﷺ lifetime, probably because of drought, scant rainfall, and the blockage of the routes between Madinah and Syria from which provisions used to arrive.
The people therefore came to the Messenger of Allah ﷺ asking him to fix the prices of provisions—setting for the traders a specific price and a definite profit margin they could not exceed. The Prophet ﷺ, however, returned the matter to its true source: Allah is the One who disposes; He is al-Qābiḍ who constricts His servants and al-Bāsit who expands their provision in accordance with the wisdom He has decreed.
Restricting people and curbing their transactions would be an injustice to them. “I therefore hope that Allah the Exalted will take me to the Highest Company while none of you can claim from me any injustice regarding blood or wealth.”
