The Ministry of Interior announced the execution in a statement published by the Saudi Press Agency, SPA, on Wednesday.
According to the ministry, the two convicted persons were identified as Nazrul Islam Abdul Basir and Siti Akhtar, both nationals of Bangladesh.
The ministry said security operatives arrested the duo after they were caught engaging in what it described as indecent acts inside a mosque in Mecca, an act considered a grave desecration of a place of worship.
Following their arrest, the suspects were subjected to investigation and subsequently charged to court.
The court found them guilty and sentenced them to death under ta'zir, which is a discretionary punishment under Islamic law applied for offences that violate public morality and sanctity.
The ministry explained that the court imposed the death penalty due to the seriousness of the offence, particularly because it was committed inside a mosque in Mecca and violated the holiness of the worship centre.
It added that the judgment became final after it was upheld on appeal by the competent judicial authority, after which a royal order was issued approving the execution.
The sentences were carried out on Wednesday, October 14, 2026, in the Mecca region.
In its statement, the Interior Ministry reiterated the commitment of the Saudi government to preserving security, upholding justice and protecting the sanctity of mosques.
It warned that anyone found committing similar offences that desecrate places of worship would face severe punishment in accordance with the Kingdom's laws.
