The author of the marginal commentary said: “It is not part of the sunnah to refrain from eating wholesome foods.” This is correct; rather, it is part of the sunnah to eat wholesome foods. Fine dates were brought to the Prophet ﷺ, and he asked where they had come from. They said, “We used to exchange one sāʿ of these for two sāʿs, and two sāʿs for three.” (2) He did not object to their eating good food; rather, he objected to their engaging in usury, and approved of their choosing the finest dates for him.
The People of the Cave said [18:19]. Thus, scrupulously refraining from wholesome foods is contrary to the sunnah of the earlier and later generations. However, if eating wholesome foods entails exceeding the bounds of extravagance, then it is prohibited—not because it consists of wholesome foods, but because of the extravagance.
His statement: “Part of extravagance is to eat everything one desires.” Glory be to Allah! This is not extravagance; rather, it is enjoyment of Allah’s blessings. Yes, if a person chooses expensive things that are not befitting someone of his standing, then this is correct. Thus, the author’s statement is open to question.
His statement: “Whoever exhausts his good things in this worldly life and enjoys them will have his ranks diminished in the Hereafter, according to the reports.” There is no doubt that if he becomes distracted by the pleasures of this world from the deeds of the Hereafter, this is undoubtedly a grave harm.
