The Prophet ﷺ mentioned the prayer one day and said, "Whoever guards it diligently, it will be a light, a proof, and a means of salvation for him on the Day of Resurrection. Whoever does not guard it will have no light, no proof, and no salvation, and he will be on the Day of Resurrection with Qarun, Pharaoh, Haman, and Ubayy bin Khalaf."
عن النبي ﷺ أنه ذكر الصلاة يوما فقال: من حافظ عليها كانت له نورا وبرهانا ونجاة يوم القيامة، ومن لم يحافظ عليها لم يكن له نور ولا برهان ولا نجاة، وكان يوم القيامة مع قارون وفرعون وهامان وأبي بن خلف.

Its chain is hasan because of Isa bin Hilal Sadafi, for his hadith is hasan.Haythami said in Majma al-Zawaid (1/292), "Ahmad and Tabarani reported it in Kabir and Awsat, and the men of Ahmad's chain are trustworthy."Munziri mentioned it in Targhib wa Tarhib (839) and said, Ahmad reported it with a good chain.
