Question: A plot was fixed for a mosque but is in use as a cycle stand since long. Can this plot be substituted by another one for the mosque?
    Answer: Yes, the plot reserved for the mosque can be substituted by another one. And, if the circumstances are such that the mosque can no longer be built, the plan can be annulled even without providing an alternative space. It all depends on circumstances and changing plans in this regard is absolutely permissible.
