What is the ruling on the Hajj of a woman in postnatal bleeding (nifas), a woman with irregular vaginal bleeding (istihada), a breastfeeding woman, a pregnant woman, and a woman who cannot find someone to care for her children?

A free, accountable woman is obligated to perform Hajj when she meets the conditions of istita'ah (ability), which includes the presence of a mahram, even if she is menstruating, or in postpartum bleeding (nifas), or breastfeeding, or pregnant, unless she is observing the iddah (waiting period) after her husband's death, in which case she is not permitted to leave. However, Hajj is not obligatory for her if she is heavily pregnant and unable to perform it, or a breastfeeding mother who cannot perform Hajj with her infant, or a woman with dependents who cannot find someone to care for them, due to the absence of the condition of istita'ah. Among the conditions of istita'ah are also physical health and the availability of funds for the maintenance of those she is obligated to support.
