I divorced my wife three times due to diabetes which causes me to lose my temper. Can I take her back?

If the case is as mentioned in the question—that the petitioner told his wife on these three occasions, "You are divorced" when he was in a state of illness which prevented him from exercising self-control and therefore lost his temper and pronounced the divorce statement, then none of these divorce statements has effected divorce on any of these occasions.

Based on the above, the marital relationship between the petitioner and his wife is still effective and standing.

God the Almighty knows best.
