Nasai

(1) The aforementioned narration has been declared weak in its chain of transmission by the researcher of the book, and he has further written that Imam al-Bukhari rahimahullah has mentioned it in a suspended (mu‘allaq) form before the Book of Clothing. However, other researchers have graded it as hasan (good) due to supporting narrations and corroborating reports. Therefore, based on the evidences, this narration is, in principle, of the hasan (good) category. For details, see: (Dhakheerat al-‘Uqba Sharh Sunan al-Nasa’i: 23/59, 60; al-Mawsu‘ah al-Hadithiyyah Musnad al-Imam Ahmad: 11/294, 295, 312, 313; Hidayat al-Ruwat: 4/217, 218).

(2) By extravagance (israf) is meant spending more than necessity or spending on what is unlawful (haram). And by arrogance (takabbur) is meant to consider others insignificant, especially those who are of a lower status than oneself in matters such as food, drink, clothing, etc.

Commentary:
Benefits and Issues:

➊
Islam does not call towards abandoning the world or monasticism, rather it forbids earning and spending through unlawful means.

➋
Spending on oneself, one’s wife and children, parents, and relatives, and fulfilling their lawful needs is an act of righteousness.

➌
The meaning of extravagance (israf) and wastefulness (tabdheer) is to spend excessively even in a lawful place. Simplicity is the hallmark of a Muslim.

➍
Even spending a little in an unlawful place is a sin and falls under tabdheer, about which Allah the Exalted has said:
﴿إِنَّ المُبَذِّر‌ينَ كانوا إِخوانَ الشَّياطينِ ۖ وَكانَ الشَّيطانُ لِرَ‌بِّهِ كَفورً‌ا ﴾ (Bani Isra’il 17:27)
“Indeed, the wasteful are brothers of the devils, and Satan is ever ungrateful to his Lord.”

➎
Preparing an excessive amount of food for a few guests and then wasting it is also included in tabdheer. Similarly, spending one’s wealth on useless entertainment that wastes time is also included in this.

➏
Extravagance and wastefulness are generally done to show superiority over others, which itself is a sin. If the money spent on such things is used to help the poor, both worldly and hereafter benefits will be attained.

➐
Our esteemed researcher has declared the aforementioned narration weak in its chain (sanadan). He writes that Imam Bukhari also mentioned this narration in a suspended (mu’allaq) form before Kitab al-Libas, and further writes that there are mawquf (stopped at the Companion) supporting narrations in Taliq al-Ta’liq and others. Therefore, from this and the discussion of other researchers, it is known that despite the aforementioned narration being weak in its chain, it is still actionable.
