Is the statement of Ibn ʿUmar: "Nothing of this world befalls a servant except that it diminishes his standing with Allah, even if he is honorable in Allah's sight" an independent juristic opinion (ijtihad) from him? And does it mean that enjoying good things (al-ṭayyibāt) diminishes a servant's status with Allah, considering that many Companions were wealthy and reached the highest ranks, and that Allah has made good things lawful?

There is no harm for a Muslim to enjoy permissible and good things if he offers gratitude for them and does not excessively indulge in them. The Holy Quran permits good things for believers in this world. The Prophet, peace and blessings be upon him, preferred wealth accompanied by piety and good health. The grateful rich person who fulfills the rights of Allah and people will not have his reward diminished in the Hereafter.

Scholars have debated which is superior: the patient poor person or the grateful rich person. The correct view is that the more pious of them is superior, for faith and piety are the basis of superiority, not wealth or poverty. This is supported by the fact that there were both rich and poor among the Prophets and the Companions.

As for the verse: ﴿You have exhausted your good things in your worldly life and enjoyed them﴾, it pertains to disbelievers who consumed good things in an unauthorized manner, which prevented them from the delights of the Hereafter, unlike believers for whom the delights of both this world and the Hereafter are combined if they utilize good things to worship Allah.
