Is it permissible to visit the husband's grave after the 'iddah period ends, and does the marital bond continue between the spouses after the 'iddah?

The 'iddah (waiting period) for widowhood is a consequence of the legitimate marital contract and ends with the completion of the 'iddah. As for visiting the husband's grave after the 'iddah has ended, it falls under the ruling for women visiting graves. The preponderant opinion is that it is permissible, provided that Islamic guidelines are adhered to, such as covering oneself, not doing it excessively, and avoiding ostentation, wailing, and seeking help from the deceased.
