Describing Allah as al-Mus'ir (the One who sets prices) and the meaning of the hadith regarding price increases

Question:
Honorable Shaykh, a hadith is narrated from the Prophet (peace and blessings be upon him) that one of the Companions came to the Prophet (peace and blessings be upon him) and said, "O Messenger of Allah, I want to buy grain, so please lower the prices for us, O Messenger of Allah?" He (peace and blessings be upon him) said: So is Allah described as al-Mus'adid (the Helper)?

Answer:
The Prophet (peace and blessings be upon him) clarified this at the beginning of the speech: He is al-Khafid al-Basit al-Mus'ir. This means that He raises prices and lowers them by the command of Allah (Glorified and Exalted is He). Al-Mus'ir is not among the names of Allah; rather, al-Khafid al-Basit is among His names. However, he said al-Mus'ir in response to them, because they said, "The price has risen, O Messenger of Allah." This was his answer to them.
