Unfortuantely I wasn’t able to find the actual hadith this Supplication is quoted from in the references available to me. But ref  cites the following,
- Al-Hakim who graded it authentic and Ath-Thahabi agreed 2/100, and Ibn As-Sunni (no. 524). Al-Hafidh graded it good in his checking of Al-‘Athkar 5/154. Ibn Baz said in Tuhfatul- ‘Akhyar p. 37, that An-Nasa’i recorded it with a good chain of narration.
- “Fortress of the Muslim, Invocations from the Qur’an and Sunnah”. Compiled by Said bin Wahf Al-Qahtani. Darussalam. 7th Edition July, 2006. pg 200.
