Is it true that whoever recites after Fajr prayer six times: "There is no god but Allah alone, He has no partner. To Him belongs sovereignty as the One God, the Self-Sufficient Master whom all creatures need, who has not taken a wife or a son, and there is none co-equal or comparable to Him," will receive the reward of forty thousand good deeds?

The summary of the answer: A hadith (definition) was reported with the wording: "Whoever says after the Fajr prayer: 'I bear witness that there is no god but Allah alone, without partner, the One God, the Self-Sufficient, Who has taken neither wife nor son, and there is none comparable to Him,' Allah will write for him forty thousand good deeds." Al-Suyuti attributed it to Ibn al-Sunni. It was also narrated by Ahmad and al-Tirmidhi, but not restricted to the Fajr prayer. Al-Tirmidhi said about it: "This hadith is gharib (uncommon); we do not know it except from this chain of narration, and Khalil ibn Murrah is not considered strong by hadith scholars. Muhammad ibn Isma'il said: 'He is munkar al-hadith (one whose narrations are rejected).'" There is another defect in it, which is the inqita' (disconnection) between Al-Azhar ibn Abdullah and Tamim al-Dari. Al-Albani declared it weak.
