because Allah, Exalted is He, says: “Indeed, He does not love those who are extravagant.” [al-A‘raf: 31]
Every pure vessel, even if valuable …
His statement, “Every pure vessel,” excludes what is impure, for it is not permissible to use it because it is filthy. What the author has said, however, requires qualification, since an impure item may be used if it is used in a manner whereby its impurity does not spread.
The evidence for this is the hadith of Jabir, may Allah be pleased with him: when the Prophet, peace and blessings be upon him, conquered Mecca, he said, “Allah has forbidden the sale of wine, carrion, swine, and idols.” They said, “O Messenger of Allah, what about the fat of carrion? Ships are coated with it, hides are greased with it, and people use it for lamps.” He replied, “No, it is forbidden.” (1) The Prophet, peace and blessings be upon him, approved of this use, even though these things are impure. This shows that there is no harm in benefiting from an impure substance when it is used in a manner whereby its impurity does not spread. An example is making an impure basket in which to carry earth and the like, in a manner whereby its impurity does not spread.
His statement, “even if valuable”: the word “even if” indicates a point of disagreement. The meaning is that even if it is expensive—such as vessels made of jewels, emeralds, diamonds, and the like—it is permissible to acquire and use it.
Some scholars held that it is not permissible to acquire or use valuable vessels because of the arrogance and extravagance involved. (2) According to this view, their prohibition is due to an external reason, not because of their inherent nature: namely, because they constitute extravagance and lead to arrogance and boastfulness, not because they are valuable.
