Wa `alaykum as-Salamu wa Rahmatullahi wa Barakatuh.

 

In the Name of Allah, Most Gracious, Most Merciful.

 

All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.

 

As long as you have done your best to observe the rules of purification in your given circumstance, you are not at fault. Allah tells us, “Be mindful of Allah as best as you can.” We are also told, “Allah does not place on anyone a burden that he or she is not able to bear.”

Moreover, the Prophet (peace be upon him) said, “If I order you something, do it as best as you can.”

 

Based on these, according to the rules of jurisprudence, “the law is relaxed in case of (unavoidable) hardship.”

 

So, you are excused as long as you have done your best to pray in a state of purity.

 

Allah Almighty knows best.
