The government order says candidates applying for the post must reveal their marital status and all those with two living wives would not be eligible. Women candidates married to a man with two surviving have also been barred from applying.
The notice for appointment of 3,500 Urdu teachers in primary schools was issued recently.
The Muslim Personal Law Board has said the order was violative of Islamic law and rights of Muslims.
"If the government has other issues, we can think of solutions," he said.
Reached for comments, UP Basic Education Minister Ahmad Hasan said the condition has been imposed to prevent confusion over who should get pension in the event of the employee's death.
Mahali, however, offered a solution to end the confusion, saying if a Muslim employee leaves behind two wives, the government can divide the pension between the two.
An Education department official said the provision was not meant for Urdu teachers alone but government teachers.
