Why have questions numbered "2428617" regarding how to dispose of forbidden Quranic plaques, and "2428875" concerning the ruling on completing studies at a mixed-gender university under special circumstances, not been answered, despite exceeding the specified time limit for a response?

If the hanging of Quranic plaques is forbidden, then it is not permissible to sell them for hanging, even at the same price they were bought for; because "everything whose use is forbidden, its sale is forbidden," due to the Prophet's (peace be upon him) saying: "Indeed, when Allah forbids something, He forbids its price." However, if they are used in a permissible way other than hanging, then it is permissible to sell them.
