Placing a stone engraved with the date of the mosque’s construction in the mosque

Question

In the mosque, too, people have a stone engraved and put it up, and they also write the Hijri year. Is this permissible or impermissible?

Answer

There is no harm in having the date of the construction of a mosque and the like engraved in stone and put up, but not in such a place that the eye falls on it during the prayer.
