Translation:

234. If any of you die and leave widows behind they shall wait concerning themselves four months and ten days: when they have fulfilled their term there is no blame on you if they dispose of themselves in a just and reasonable manner. And Allah is well acquainted with what ye do.

Notes (Tafseer)

267. The 'Iddat of widowhood (four months and ten days) is longer than the 'Iddat of divorce (three monthly courses, ii. 228). In the latter the only consideration is to ascertain if there is any unborn issues of the marriage dissolved. This is clear from xxxiii. 49, where it is laid down that there is no 'Iddat for virgin divorces. In the former there is in addition the consideration of mourning and respect for the deceased husband. In either case, if it is proved that there is unborn issue, there is of course no question of remarriage for the woman until it is born and for a reasonable time afterwards. Meanwhile here maintenance on a reasonable scale is chargeable to the late husband or his estate.
