I have a problem in my back which many times causes me not to be able to bow, so i’m not able to touch my feet while making wudu. May I do tayyammum in these situations?
Shaikh Adel As-Sayed:
This is not a reason to make tayyamum. Prophet Muhammad, peace be upon him said:
اتقوا الله ما استطعتم
Meaning: “Be obedient and pious to Allah as much as you can”
There could be solutions for this, for example she might put a bowl with water in the floor and wash her foot there.
