This fatwa explains that with one tayammum, it is only permissible to perform one obligatory prayer. It is not allowed to pray more than one obligatory prayer with the same tayammum, whether the prayers are in the same time or different times. However, a person may pray as many voluntary prayers as they wish with one tayammum. This Islamic ruling is mentioned by Imam al Shafi and explained by Imam al Imrani. Islamic scholars clearly state that this rule applies only to obligatory prayers, not voluntary ones. This fatwa is part of the Shafi school of Islamic law and shows the clear opinion of Islamic scholars on this issue.
