سألت النبي صلى الله عليه وسلم عن الكلمات التي تلقاها آدم من ربه فتاب عنه، فقال: قال: بحق محمد، وعلي، وفاطمة، والحسن، والحسين، إلا تبت علي. فتاب عليه.
I asked the Prophet salla Llahu ‘alayhi wa sallam regarding the “kalimat (words)” that Adam received from his Lord; by which Allah subsequently accepted his repentance (referring to verse 37 of Surah al Baqarah). He said, “(He asked) by the rights of Muhammad, ‘Ali, Fatimah, Hassan, and Hussain; (Adam said) except that You accepted my repentance. And so Allah accepted his repentance.”
Al Daraqutni (and Ibn al Jawzi in a similar manner) and others narrate from Hussain al Ashqar — ‘Amr ibn Thabit narrated to us — from his father — from Sa’id ibn Jubayr — from Ibn ‘Abbas.
‘Amr ibn Thabit is not a thiqah (reliable). In fact, Ibn Hibban says, “He was of those who would narrate mawdu’at (fabrications). It is not permissible to mention his name except for the sake of i’tibar (consideration).”
Al Hussain ibn Hassan al Ashqar is da’if (weak). Some have even accused him of lying.
Ibn al Jawzi, al Suyuti, Ibn ‘Iraq, and al Shawkani mention this hadith in their respective works on mawdu’at (fabrications).
 Ibn al Jawzi: Kitab al Mawdu’at, 2/3.
 Ibn al Jawzi: Kitab al Mawdu’at, 2/3; al Suyuti: al Laʾali al Masnu’ah, 1/369 and al Ziyadat ‘ala al Mawdu’at, 1/245; Ibn ‘Iraq: Tanzih al Shari’ah, 1/395; al Shawkani: al Fawaʾid al Majmu’ah, hadith no. 341.
