Is praying in front of non-Muslims to introduce them to Islam considered showing off, and does it contradict the intention of sincerity required in prayer?

It is permissible for Muslim students to perform prayer in front of non-Muslims to show them how Muslims pray, and this is not considered showing off (riya') if the intention is purely for Allah Almighty and the aim is to clarify the truth of Islam. The Prophet, peace and blessings be upon him, prayed on the minbar so that people could learn his prayer, and demonstrating good deeds for others to emulate is prescribed. Jurists have stated that adding the intention of teaching prayer does not invalidate it, for indeed, non-believers witnessing Muslims praying with devotion might be a reason for them to embrace Islam.
