What can someone, who is in a state of ritual impurity, do when he is unable to perform Ghusl before his prayers will become Qadha? Will normal ablution suffice if clean sand for Tayammum is not readily available?
When Ghusl is not possible, Tayammum must be performed to perform the obligatory Prayer within its time. Tayammum can be performed on any material of earth e.g. dry soil. Sand, stones, dust, etc. Wudhu does not suffice when Ghusl is not possible, but Tayammum is the only alternative.
Wassalam.
