Is a daughter considered disobedient and deserving of God's wrath and Hellfire if her mother wrongs her, curses her, and prefers her siblings over her despite her dutifulness towards her, which sometimes causes her to raise her voice, then she regrets it and apologizes?

If a mother prefers some of her children over others, or curses them without justification, then she is unjust. However, this does not nullify her right to dutifulness, nor does it permit raising one's voice at her. The obligation is to be dutiful to her and obey her in what is right, and to advise the sisters and warn them against being undutiful to their mother. If you fulfill your duty to your mother, you will not be undutiful, and her supplication against you will not harm you, Allah willing. Repaying evil with good brings affection and wards off the evil of Satan. "And not equal are the good deed and the bad. Repel [evil] with that which is better, and thereupon the one whom between you and him is enmity [will become] as though he was a devoted friend." [Fussilat: 34]. Be assured of good through the blessing of your dutifulness to your mother, for it is one of the most beloved deeds to Allah and one of the greatest causes of His pleasure.
