Recite Alhamdulillah it is equivalent to giving 100 horses in jihad .is the above Hadith authentic .does shoaib arnaout rahimaullah have classified above Hadith authentic.please answer this question so that we can perform this and get the reward

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad, is His slave and Messenger.

This Hadeeth was classified as Hasan (Sound) by a group of scholars, and therefore there is nothing wrong with acting upon it. It was classified as Hasan by Al-Munthiri and Al-Haythami, and As-Suyooti reported that Al-Haakim classified it as Saheeh (Authentic).

According to the sources that we consulted, Shaykh Shu‘ayb Al-Arnaa’oot classified it as Weak in his revision of Al-Musnad, saying: “Its chain of narration is weak due to the weakness of the narrator Abu Saalih, who is Baathaam, or Baathaan, the freed slave of Umm Haani’.” [End of quote]

It was also classified as Weak by Shaykh Al-Albaani in Dha‘eef Al-Jaami’, but he later changed its classification to Hasan in As-Silsilah and underlined that Abu Saalih was most likely Thakwaan As-Sammaan, who was one of the reporters approved by Al-Bukhari and Muslim .

Allah Knows best.
