A person is out and he is not in the state of Taharat when the time for prayer begins. Does he have to do both Tayamum and Wudu or just Tayamum if water is accessible?
Bismihi ta'ala
As you would know, tayamumm is only done when one has no access to any water or using of water is harmful, like a sickness or extremely cold weather.
In any other case, especially if water is accessible, the mukallaf must do wudhu.
And Allah knows best.
