Issue No.1773- From the point of usury, barley and wheat are commodities of one and the same sort. Hence, one cannot exchange 10 kgs of wheat for 12 kgs of barley, and vice versa. Even if one buys 10 kgs of barley on the condition that he would give in exchange 10 kgs of wheat at the time of its harvest, it is also haram, because he has taken barley on the spot and will give wheat some time later, and this amounts to taking something in excess.

Issue No.1786- Transactions on endowed property are void. However, if it is spoiled to the extent that it cannot be used for the purpose which it was endowed for, like, if the carpet of a mosque is in a bad state that it is not possible to perform prayer on it, there is no objection in selling it. Similarly, old building materials which are no longer needed for reconstruction of the mosque, can be sold and the money acquired in this way should be spent in the same mosque for the same purpose.
