I say: This chain of transmission is very weak. However, it has corroborating reports indicating that it has an underlying basis in the hadiths of Abdullah ibn Mas'ud and al-Bara' ibn Azib. As for the hadith of Ibn Mas'ud, it was recorded by al-Tayalisi (378), al-Tabarani, and others. Al-Hakim declared it authentic, but al-Dhahabi rejected it, as I explained in al-Rawd al-Nadir (651). Yet it has another route through which it is strengthened; I documented it there. As for the hadith of al-Bara', it was recorded by Ahmad (4/286), Ibn Abi Shaybah in al-Iman, no. 110—edited by me—and Ibn Nasr in Kitab al-Salah (folio 91/1), through the narration of Layth ibn Abi Sulaym, who is weak.

I say: Taken together, the hadith’s routes rise to the level of good, at the very least. And Allah knows best.

1729 — “I advise you not to be one who curses frequently.”

Ahmad recorded it (5/70): Abd al-Samad narrated to us; Ubayd Allah ibn Hawdhah al-Quray'i narrated to us that he said: A man who had heard Jarmaz al-Hujaymi narrated to me that he said, “I said: ‘O Messenger of Allah, advise me.’” He then said the above. Al-Tabarani also recorded it (no. 2181) through another route from Abd al-Samad ibn Abd al-Warith, with the same chain.

I say: Its chain of transmission is authentic were it not for the unnamed man. However, al-Hafiz stated in al-Isabah: “Al-Baghawi and Ibn al-Sakan definitively identified him as Abu Tamimah al-Hujaymi.”

I say: If this is established, then the chain is authentic, because Abu Tamimah—whose name was Tarif ibn Mujalid—was trustworthy and among al-Bukhari’s narrators. Moreover, Ibn al-Sakan recorded it through Salm ibn Qutaybah, who is trustworthy and is also among al-Bukhari’s narrators—
