Issue 357: There is no difference between the Tayammum performed instead of Wudhu and the one performed instead of Ghusl.

Issue 358: Things which invalidate Wudhu, also invalidate the Tayammum performed instead of Wudhu.

Issue 359: Things which invalidate a Ghusl, also invalidate the Tayammum performed instead of it; for instance, if one performs Tayammum instead of Janabah Ghusl, and after a while they become Junub again, their Tayammum will be void.

Issue 360: Tayammum will be valid only if performing Wudhu or Ghusl is not possible. So, if one performs Tayammum with no excuse, it will not be valid. Nor will it be valid if the excuse to perform Tayammum is no longer there, for example, if water has not been available, but now it is.

Issue 361: If a person performs Tayammum instead of Janabah or any other Ghusl, they will not need to perform Wudhu for prayers.

Q362: Is it permissible to enter a mosque and attend the congregational prayers having performed Tayammum instead of Janabah Ghusl?

A: As long as the excuse to perform Tayammum (except for the case of being short of time) is there, it is permissible.

Q363: Is it permissible for soldiers who are guarding a place and have not performed Wudhu, and it is still not possible for them to perform Wudhu or Tayammum, to say prayers without Wudhu or Tayammum? If so, must they offer the Quadha prayers later?

A: In such a situation, as an obligatory precaution, they must say their prayers without Wudhu and Tayammum, and offer the Quadha prayers later.
