Ruling on one who feels exhausted before completing tawaaf
Question

I am a woman who suffers from illness. I went for ‘umrah and when I had done three circuits of tawaaf, I began to feel dizzy. What should I do?
Praise be to Allah.You should rest and then complete your tawaaf. If a long time elapses, then you must start tawaaf again from the beginning. But if your dizziness goes away quickly and easily, then complete your tawaaf and that will be sufficient, praise be to Allah. End quote.
