«آدِي السَّما وآدِي الْأَرْضْ»

The proverb describes a search that cannot succeed, however far it extends. The obstacle is not a lack of effort or places to look: the desired thing cannot be found.

It can also offer consolation after the loss of a child. In that setting, its emphasis falls on accepting what searching cannot restore and finding the patience to bear the loss.

It may be used when someone persists in seeking something unobtainable, rather than something merely difficult to find. If offered to a person grieving a child, it is meant to encourage patience, though its directness calls for care.
