Does Allah Almighty build a palace in Paradise called the Palace of Praise for one whose wife has died and who has been patient and sought reward, or is that limited to one whose child has died?

We ask Allah to have mercy on your wife. The Hadith that mentions "Bayt Al-Hamd" (House of Praise) refers to the reward for patiently enduring the death of a child. It may also include anyone whose beloved has died, and they praised Allah and said "Inna Lillahi wa inna ilayhi raji'un" (Indeed, to Allah we belong and to Him we shall return). This is based on the Prophet's (peace be upon him) saying: "My believing servant has no reward from Me except Paradise when I take his beloved one from the people of the world and he endures it patiently, seeking My reward." The beloved one refers to someone cherished, like children, siblings, or anyone a person loves. Endurance here means bearing the loss patiently, hoping for reward from Allah. Remember the words of Allah Almighty: "And give good tidings to the patient, Who, when disaster strikes them, say, 'Indeed we belong to Allah, and indeed to Him we will return.' Those are the ones upon whom are blessings from their Lord and mercy. And it is those who are the [rightly] guided."
