Wearing a belt to secure the izar (lower garment) during احرام is permissible جمہور علماء کے مطابق. Sheikh Ibn Baz explicitly ruled that using a belt, cord, or similar fastener to keep the izar in place is allowed, as the prohibition in احرام concerns garments tailored and stitched to fit the body's contour (such as pants, shirts, and robes), not accessories used to fasten the احرام cloth. نبی کریم (صلی اللہ علیہ وسلم) prohibited the muhrim from wearing shirts, trousers, turbans, hooded cloaks, and leather socks, but did not mention belts or waist fasteners.
Sheikh Ibn Uthaymeen similarly permitted money belts and waist pouches worn during احرام for safekeeping money, documents, and identification. He noted that حجاج need a secure way to carry their valuables, and a money belt serves this practical purpose without violating the spirit or letter of احرام restrictions. The Permanent Committee for Scholarly Research and Ifta also issued a fatwa permitting belts during احرام.
There is a minor difference of opinion among some scholars regarding whether the belt should be plain or whether it matters if it resembles regular clothing. However, the overwhelming majority agree that a simple belt, cord, or money belt is permissible. What remains prohibited is wearing any garment that is sewn to fit a specific body part, such as underwear or shorts under the izar.
