Offering Salah while standing slightly higher than the Ma'mums

Q 9: Is it permissible to offer Salah on something that is 3 cm higher than the ground?

A: There is no harm if the Imam stands slightly higher than the Ma'mums (persons being led by an Imam in Prayer) when necessary. The Prophet (peace be upon him) once ascended the minbar (pulpit) during Salah to teach people how to offer it properly.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
