What is the authenticity of the narration from Aisha: "The first affliction to occur in this Ummah after its Prophet was satiety; for when the people's stomachs became full, their bodies fattened, their hearts weakened, and their desires became wild," and the narration from Anas: "It is extravagance to eat whatever you desire"? Are there any religious texts that prohibit extravagance in eating or lack of control over it, and what was the guidance of the Messenger of Allah, peace be upon him, regarding that?

The lust of the belly is among the greatest destructive perils, as it is the cause of many spiritual and physical ailments. From it branches the lust of the private parts and the love of status and wealth, which in turn generate diseases of the heart such as arrogance and envy. Islam has encouraged moderation in eating and drinking and forbidden extravagance, citing the Almighty's saying: (And eat and drink, but be not excessive. Indeed, He likes not those who commit excess.) [Al-A'raf: 31], and the Prophet's (peace be upon him) saying: (No human ever filled a vessel worse than his stomach. A few morsels are sufficient for the son of Adam to keep his back straight. But if he must needs fill it, then a third for his food, a third for his drink, and a third for his breath.)

The Prophet’s (peace be upon him) guidance regarding food was not to refuse what was available and not to seek what was unavailable. He would eat what was easy to obtain and be patient if food was scarce. Scholars have mentioned the benefits of moderation in food, including: purity of heart, kindling insight, humility before God, remembering the trials of the Hereafter, breaking the desires for sins, preventing sleep, and maintaining bodily health.

As for the hadith of Aisha (may Allah be pleased with her): (Indeed, the first trial that occurred in this Ummah after the passing of its Prophet (peace be upon him) was gluttony), and the hadith of Anas ibn Malik (may Allah be pleased with him): (Indeed, it is extravagance to eat everything you desire), both are weak and not authentic.
