In principle,
the obligation of Salah is not removed from Muslims as long as they are sane. The woman in question had to perform Salah according to her own condition, even if she could not make Wudu’ due to her illness, or could not do Taymmum, or if there was impurity on her body or clothes that she could not remove or wash. Allah (Exalted be He) says:
Allâh burdens not a person beyond his scope.
He also says:
So keep your duty to Allâh and fear Him as much as you can
In such a case, she should perform Salah while she is standing if she is able to; otherwise, she should perform it while she is sitting. If she is unable to, she should perform it while lying on her side or while she is sleeping on her back if she cannot lean on her side. (Part No. 6; Page No. 385) Allah (Exalted be He) says:
So keep your duty to Allâh and fear Him as much as you can
He also says:
Allâh burdens not a person beyond his scope.
Also, the Prophet (peace be upon him) said to a sick person:
“Offer Salah standing and if you cannot, then sitting; and if you cannot, then lying on your side.”
According to another narration, he (peace be upon him) added:
“…and if you cannot, then lying on your back.”
Thus, it is obligatory on that woman to make up for the Salah she missed in order, i.e. she should begin with the obligatory Salah she missed on the first day and so on until she completes them.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
