All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.
First of all, we ask Allaah to help you to be patient and greatly reward you. You should know that this worldly life is a test whereby Allaah tests His Slaves with good and bad, and the affliction is not necessarily due to a sin that a person has committed.
Allaah may afflict a person in order to test him, and then if this person is patient, Allaah would increase his status and wipe out his sins. Therefore, we advise you to be patient; for more benefit on the excellence of patience, please refer to Fatwa 83577.
Being anxious does not help and only worsens the situation. Instead, you should remember that Allaah might have repelled evil from you as a result of these afflictions.
We also advise you to look for a pious husband as this is Islamically permissible; for more benefit, please refer to Fatwa 82471.
However, you should not hasten to accept anyone who proposes to marry you unless you inquire about him from trustworthy and pious people who know him and then perform the Istikhaarah prayer; for more benefit on the Istikhaarah prayer, please refer to Fatwa 81434.
It should be noted that the third divorce makes a woman irrevocably divorced from her husband unless she marries another man [a sincere marriage and he consummates the marriage with her and then he divorces her or dies], as stated in the Quran. So, the matter of remaining married after a third divorce takes place does not depend on the husband or the wife. It seems that you already know this, but this is just a reminder.
Allaah Knows best.
