A woman was divorced Islamically in October and performed temporary marriage after the Iddah ended in January. In February, she found out that her ex-husband had read the divorce incorrectly. What should she do?
Bismihi ta'ala
The first husband must redo the Islamic divorce, making sure all the requirements are met, and it would be best that he authorises a scholar to conduct the divorce on his behalf.
As for the woman, although her temporary marriage was not sinful, it could be that she is not permitted to marry or be with that second man she was with in the temporary marriage. This is something that she must refer to her Marja' taqleed about.
And Allah knows best
