Do the mentioned events concerning the mother's death indicate God's forgiveness for her, despite her not praying and her insulting her husband?

Abandoning prayer is a great danger, and the inability to remove impurity is not an excuse for abandoning it; rather, a person must purify themselves and pray. For someone who dies on Friday night, this is considered a sign of a good ending, based on the hadith: "No Muslim dies on Friday day or Friday night except that Allah protects him from the trial of the grave." The good praise of people for the deceased, if they are people of goodness and righteousness, is also a sign of good, based on the hadith: "You are Allah's witnesses on earth." Burying a child with the deceased woman is disliked by some scholars and considered forbidden by others, except out of necessity, as jurists believe that two should not be buried in one grave unless there is a need.
