Can a woman who has her period make a conditional intention for umrah at the miqat, and what is the ruling on a conditional intention?

Summary

Menstruation, postnatal bleeding and major ritual impurity do not prevent a person from making the intention of ihram for hajj or umrah, but purity is required during prayer and tawaf. A conditional intention is permitted based on the hadith of Dhuba'ah, whereby a person may stipulate that they will exit ihram if illness or an obstacle occurs. When the condition is met, the person exits ihram with the intention and shaving or trimming the hair, and no dam is due unless the exit was stipulated with a dam.
