O Prophet! When you divorce women, divorce them at their ‘Iddah (prescribed periods), and count (accurately) their ‘Iddah (periods ). And fear Allah your Lord (O Muslims), and turn them not out of their (husband’s) homes, nor shall they (themselves) leave, except in case they are guilty of some open illegal sexual intercourse. And those are the set limits of Allah. And whosoever transgresses the set limits of Allah, then indeed he has wronged himself. You (the one who divorces his wife) know not, it may be that Allah will afterward bring some new thing to pass (i.e. to return her back to you if that was the first or second divorce).
Meaning:-
Iddah or Iddat (Arabic) (period of waiting) : is the period a woman must observe after the death of her spouse or after a divorce, during which she may not marry another man. Its purpose is to ensure that the male parent of any offspring produced after the cessation of a nikah (marriage) would be known.
Transgresses: to violate a law, command, moral code, etc.; offend; sin.
