Will the husband be punished for his negligence in prayer, and will he be in the Hereafter, taking into account that he was characterized by noble morals, and based on a Hadith from the Messenger that those with noble morals will be with him on the Day of Resurrection?

We ask Allah the Almighty to forgive your deceased. One who abandons prayer is not considered a disbeliever by the majority of scholars, but rather a transgressor, and this is the preponderant opinion. The doctrine of the Sunnis is that whoever dies a monotheist, having committed some major sins, is subject to Allah's will. There is hope for this deceased person's forgiveness from Allah, especially since he was of good character, for indeed, the two things that most admit people to Paradise are piety towards Allah and good character. Strive in supplicating for him and giving charity on his behalf. A Muslim woman will be a wife to her husband in Paradise if both enter it and she did not marry after him.
