It is narrated from Hazrat Sa'id bin al-Musayyib (may Allah have mercy on him) that he said: If a husband divorces (his wife) through a letter, then takes her back (revokes the divorce), but the letter of revocation does not reach the wife and she marries another man, if the (first) husband reaches her before consummation (with the second husband), then the wife will remain his; otherwise, she will not.
