I think it’s high time for Muslims to have a serious conversation about the halalness of industries and products that so overtly exploit and exacerbate insecurities.
Someone interested in īmān & the branches of faith/shuʿab al-īmān would ask whether the beliefs behind this and similar products are truly compatible with īmān and whether products that build upon and perpetuate those beliefs could ever truly be halal.
Someone interested in iḥsān and spiritual excellence would ask whether the underlying spiritual defects driving such a product and the spiritual damage it promotes could ever leave such a product certified to be halal.
Someone interested in islām and legal praxis would ask whether products that deceive customers with unproven claims of efficacy and which enable customers to deceive themselves and others—in addition to what has already been mentioned—could ever truly be halal.
A contemporary maqāṣidist would point to all the cash leaving the pockets of the poor and entering the coffers of the rich as proof that it’s in line with contemporary maqāṣid of protecting property/māl. However, anyone interested in classical maqāṣid al-sharīʿah would point out that such a product prolongs and increases harm to the intellect/ʿaql (the third maqṣad), that protecting harm to the intellect/ʿaql for the masses outranks protecting the profits of a relatively very small number of producers—and that’s assuming that this falls within al-maṣāliḥ al-mursalah which is most likely does not—, and then ask whether such a product could ever truly contribute to the maqāṣid of Islam.
And then there are all those things about imposing standards of beauty, and self-worth, etc, etc…
Just about anyone interested in an Islamic worldview is likely to have some questions about the halalness of this sort of product and the industry it comes from.
