All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.
This supplication is mentioned in a Hadeeth that was reported by Ibn As-Sunni in his book entitled “‘Amal Al-Yawm Wal-Laylah”, and it was also reported by others. However, it was classified as Dha’eef [weak] by As-Sakhaawi in his book entitled “Al-Maqaasid Al-Hasanah”, as well as by Shaykh Al-Albaani in his book entitled “Silsilat Al-Ahaadeeth Ath-Dha’eefah”.
Allaah Knows best.
