How authentic is the Hadith: "Allah laughs at a man who gets up on a cold night from his bed and covers, then performs ablution, then establishes the prayer..."?

The aforementioned Hadith is authentic,وقف (mauquf) on Ibn Mas'ud (may Allah be pleased with him). It was also narrated as a مرفوع (marfu') Hadith with a good chain of transmission, using the wording: "Our Lord wonders (عجِب ربنا)," and it does not contain the word "laughter."

There are other authentic Ahadith that mention Allah Almighty's laughter, including: - The Hadith of Abu Darda (may Allah be pleased with him), where the Prophet (peace be upon him) said: "Three types of people are loved by Allah, and He laughs at them and rejoices in them: a man who, when a detachment flees, fights behind them with his own soul; a man who has a beautiful wife and a soft bed, yet he rises from the night (for prayer); and a man who is on a journey and his companions stay up (talking) then sleep, but he rises at dawn (for prayer)." - The Hadith of Abu Hurairah (may Allah be pleased with him), in Sahihayn: "Allah laughs at two men, one of whom kills the other, yet both enter Paradise: one fights in the way of Allah and is killed, then Allah accepts the repentance of the killer, and he is martyred." - The Hadith in Bukhari and Muslim regarding the last person from the people of Paradise to enter Paradise, which states: "Allah عز وجل laughs at him, then grants him permission to enter Paradise."

The attribute of laughter is affirmed for Allah Almighty. We believe in it as it has been narrated, without asking how (كيف) or likening it (تشبيه) to the laughter of created beings.
