حدثنا مؤمل بن الفضل الحراني حدثنا عيسى يعني ابن يونس حدثنا جعفر يعني ابن ميمون صاحب الأنماط حدثني أبو عثمان

[Its isnad is daif] Tirmidhi narrated it in the chapter on Supplications, in the section "Allah is Huyayy and Kareem..." Hadith 3556, from the hadith of Jafar bin Maymun, with this wording, and he said, hasan gharib, but its chain is daif. The hadith has a daif corroborating narration in Ibn Hibban, Hadith 2399.
