It was recorded by al-Nasa’i (575) and Ibn Dūst al-‘Allāf in al-Amālī (folio 124/2). Al-Ḥakam was Ibn ‘Utaybah al-Kindī, a client of the Kindah tribe: trustworthy, and relied upon by both Ṣaḥīḥ collections. The same applies to Shu‘bah, namely the imam Shu‘bah ibn al-Ḥajjāj.

As for the wording cited by al-Suyūṭī in al-Jāmi‘ al-Kabīr, through the narration of Ismā‘īl ibn ‘Abd al-Ghaffār al-Fārsī in al-Arba‘īn, from ‘Amr ibn Shu‘ayb through this chain, with the wording: “Whoever says, ‘None has the right to be worshipped but Allah,’ one thousand times, will come on the Day of Resurrection with a deed surpassing every other deed, except the deed of a prophet or of a man who has said the declaration of Allah’s oneness more often”—I say: it is rejected; rather, it is false, since it contradicts these authentic transmission routes from ‘Amr ibn Shu‘ayb. Perhaps this is why al-Manāwī did not include it in his book al-Jāmi‘ al-Azhar.

Note: Ismā‘īl ibn ‘Abd al-Ghaffār is how the name appears in al-Jāmi‘ (2/808), whereas in another hadith therein (2/811), it appears as Ismā‘īl ibn ‘Abd al-Ghāfir, which is correct. This is how it appears in Shadharāt al-Dhahab, where he is mentioned among those who died in 504 AH, at the age of eighty-one. No criticism or commendation of him is mentioned there.

Know that this number—one hundred—is the highest I have found among the authentic formulas of remembrance. As for the number one thousand, I have seen it only in this rejected narration and in another hadith concerning the glorification of Allah, with a weak chain, which I documented in the other book under no. 5296.
