Sheikh ’Abdulhamid Az-Zu’kari ḥafidhahullāh said:

والله يا أخي، إن كان قد لحقكم خسائر بسبب هذا التسجيل معكم، فلا بأس أن تأخذوا العربون. وأما إذا كان لم يلحقكم خسائر، فردوا إليهم حقهم، أو خذوا بقدر خسائركم ((لا يحل مال امرئ مسلم إلا بطيبة من نفسه)). By Allāh, my brother, if you have incurred losses because of this registration, then there is no harm in taking the deposit. However, if no loss has befallen you, then return to them their due, or take only an amount equal to the loss you sustained. “The property of a Muslim is not lawful except with his willing consent.” [https://t.me/madrasatuna/5471] Sheikh Najeeb Ash-Shar’abi ḥafidhahullāh: وعليكم السلام ورحمة الله وبركاته. يجوز أخذ العربون المذكور، على القول الصحيح، بارك الله فيكم. ولي فتوى صوتية في بيان جواز حكم العربون في البيع، منشورة في القناة. [https://t.me/qweasdzxcmnblkjpoik/1629] "It is permissible to take the mentioned deposit according to the sound opinion, may Allāh bless you. I also have an audio fatwa explaining the permissibility of the ruling on ʿarbūn in sales, published on the channel (https://t.me/masjidsahabah/1415)." [WhatsApp correspondence] Sheikh Rashād Adh-Dhali'ee: "If this deposit being taken is done in the manner recognised by the Fuqaha—such that the person registering for ʿumrah with the company, for example, pays a certain portion of the total cost, and if he travels with them, he completes the payment and that deposit is counted toward the total; but if he does not travel with them—being the one who chose not to proceed—then the company becomes entitled to keep the deposit—then this transaction is permissible, and I see no issue with it. As for the claim that this constitutes selling what one does not own, it is not as such. This is not a case of selling what one does not own. The prohibition of selling what one does not own concerns goods: a specific commodity that is in someone else’s possession, which a person sells to another while it is still owned by someone else. But here, no specific commodity is being sold; rather, it is a lease contract for a service—for the provision of a future service. This contract resembles a contract of manufacture (istisnāʿ). An istisnāʿ contract is what companies or workshops enter into when a person requests, for example, the manufacture of windows, doors, cabinets, a bed, clothing, shoes, or the like, providing them part of the payment, and they prepare the product for him. The same applies in construction work: a contractor receives part of the payment and performs the work, and the employer then completes the remaining payment. Thus, what this company does in arranging the affairs of the ʿumrah—coordinating housing, transportation, and matters related to food and drink and other agreed-upon services—does not involve selling something it does not own. Rather, it is a lease for a known service: a clearly defined service, such as accommodation in specified housing, transportation in a specified vehicle, a set duration, and specified meals. It is something clear, involving neither uncertainty nor deception, and it does not fall under the category of selling what one does not own. It appears to me that this transaction is permissible and contains no objection. May Allāh bless you." [https://t.me/madrasatuna/5479]
