The addition he included may have been stolen from the report narrated by Asbagh ibn Zayd, through his chain from Ibn ʿUmar as a report attributed to the Prophet, with the wording:
“Whoever hoards food for forty nights has dissociated himself from Allah, and Allah has dissociated Himself from him …”
This is a rejected hadith, as Abū Ḥātim stated in al-ʿIlal (1/392/1174). Many leading hadith scholars identified a hidden defect in it on account of this Asbagh, though the defect actually lies with his unknown teacher. Some have erred by judging the hadith to be strong. All of this is a clear mistake, which I explained in Ghāyat al-Marām (194–195/324), where I also documented its sources and cited the scholars’ statements concerning its chain of transmission, showing the stronger views from the weaker ones in a manner not found elsewhere. And Allah is the Granter of success.
Furthermore, among the reports that support the hadith under discussion is the hadith of Maʿmar ibn Abī Maʿmar, attributed to the Prophet:
“Whoever hoards is a sinner.”
Muslim and others narrated it, and it is cited in Ghāyat al-Marām (165/325). Yet in al-Targhīb (3/26), it appears attributed to Muslim and others with the addition:
“… food!”
But this addition has no basis in any of the narrations of this hadith of Maʿmar, as I had pointed out in al-Taʿlīq al-Raghīb (3/26).
On this occasion, I say:
One matter worthy of notice is that the nisbah al-Ghusaylī in the name Ibrāhīm ibn Isḥāq was corrupted in al-Mustadrak to al-ʿUsaylī—using an undotted ʿayn in place of the dotted ghayn—as it appears correctly in al-Bayhaqī. His biographical entry in al-Mīzān states that he was a descendant of Ḥanẓalah al-Ghasīl. Al-Mundhirī mentioned him correctly in al-Targhīb, but its three annotators corrupted it (3/570), rendering it
