Answered by Sidi Suheil Laher
if i am in a state where ghusal is wajib upon me but i do not have the relevant facilities (i.e. water is far too cold and by the time it heats up, salah time will have come in) to perform ghusl and time for salah is nearly here…do i just perform wudu and perform salah or do i perform tayyammum.
jazakAllah khayr
wa`alaykum as-salam wa-rahmatullah
I hope you are well. I apologize for the delay in responding.
It is not necessary to perform ghusl before the time for the salah comes in. So, if you can heat the water, (and/or reach suitable facilities, as the case may be), and then to perform ghusl and perform at least the opening Takbir of the salah before the time for the salah ends, then that is sufficient. Even if you will miss the jama`ah for the salah, but still can catch the end of the salah time on your own after ghusl, you should do that.
However, if the time is very short, and you are genuinely afraid that after heating the water / reaching the bathing facility and performing ghusl as quickly as possible, you would still not catch even the end of the salah time, then you can immediately perform tayammum and pray, and then perform ghusl and repeat the salah. [Ref: Ibn `Abidin, Radd al-Muhtar]
And Allah knows best.
