Does a divorced woman deserve the maintenance for her waiting period (nafaqat al-'iddah) from the date the divorce is decreed until the death of her husband, or does that period transform into the waiting period of a woman whose husband has died, and thus she is not entitled to her maintenance, according to the Hanafi school of thought?

She is not entitled to any maintenance after his death. Whatever maintenance she had not received before his death is forfeited upon his death, because maintenance becomes due incrementally, and he owns nothing after his death. Her iddah continues as it is and does not change into the iddah of a widow, because she is irrevocably divorced by the judge's ruling.
