Following The Sunnah 'Collection of Beneficial Statements #6'
Shaykh ul Islaam Ibn Taymeeyah
Translated by Abbas Abu Yahya
'Products become expensive due to an increase in prices and are cheap due to a decrease of price. These two aspects are from the general occurrences which have no creator except Allaah Alone.
None of those things can occur except by Allaah's permission and His capability. However, Allaah -Subhanahu- may place some of the actions of the slaves of Allaah as reasons and means for some occurrences. Just as like a murderer killing someone is the reasons for a death to occur.
Allaah causing an increase in prices could be due to the slaves of Allaah oppressing one another and the decrease in prices could be due to some people being good to others'. [Majmoo al-Fatawa 8/519]
