Grading: This hadith is "sahih li-ghayrihi" (authentic due to supporting evidence), and this chain is "da'if" (weak).
Technical note / Defect ('illah): Amr bin Muslim (al-Janadi) is weak but usable for corroboration (yu'tabar bihi). There is a disagreement over whether this hadith is connected or mursal, as the author (al-Hakim) has pointed out.

Reference / Source: Abu Dawud (2229) and al-Tirmidhi (1185) narrated it from Muhammad bin Abd al-Rahim al-Baghdadi al-Bazzaz, from Ali bin Bahr, with this same chain. Al-Tirmidhi said: This hadith is "hasan gharib".

Details of the narration: And this narration will come after it by way of Abd al-Razzaq, from Ma'mar, from Amr bin Muslim, from 'Ikrimah, as "mursal".

Reference / Source: The basis of the hadith of Ibn Abbas (may Allah be pleased with them both) is found in al-Bukhari (5273) by way of Khalid al-Hadhdha' and (5276) by way of Ayyub: that the wife of Thabit bin Qays came to the Prophet (peace and blessings be upon him) and said: O Messenger of Allah! I find no fault with Thabit bin Qays in his character or his religion, but I dislike ingratitude (kufr) in Islam. He (peace and blessings be upon him) said: "Will you return his garden to him?" She said: Yes. He (peace and blessings be upon him) said (to Thabit): "Accept the garden and divorce her with one divorce." There is no mention of the waiting period ('iddah) in it.

Corroborating chains and supporting reports: However, the narration of Amr bin Muslim (which mentions the waiting period) is supported (shahid) by the hadith of al-Rubayyi' bint Mu'awwidh, which is in Ibn Majah (2058), al-Tirmidhi (1185) and al-Nasa'i (5662), and it is "sahih".
