هل يوجد دعاء أو آية قرآنية تساعد في بيع أرض أو بيت؟

There is no specific supplication or verse mentioned for facilitating difficult matters. However, general, comprehensive supplications have been reported from the Prophet (peace and blessings be upon him) which can be recited with the intention of facilitating matters. Among them is: "O Ever-Living, O Sustainer, by Your mercy I seek assistance. Correct all my affairs for me and do not entrust me to my soul for the blink of an eye." Among the things that help facilitate matters are piety and frequent supplication to Allah, in accordance with His saying: "And whoever fears Allah - He will make for him ease in his affair."
