If someone who cannot perform ghusl wants to perform an act for which ghusl is obligatory, he must perform tayammum in place of ghusl. If someone who cannot perform wuḍūʾ wants to perform an act for which wuḍūʾ is obligatory, he must perform tayammum in place of wuḍūʾ. Ruling 712.* If someone performs tayammum in place of the ghusl for janābah, it is not necessary for them to perform wuḍūʾ for prayers.

Similarly, [it is not necessary for them to perform wuḍūʾ for prayers] if the tayammum is in place of other ghusls – except the ghusl for medium istiḥāḍah – although in such a case, the recommended precaution is that they should perform wuḍūʾ as well; and if they cannot perform wuḍūʾ, they should perform another tayammum in place of wuḍūʾ.
