Arba'un 39 — God pardoned my community error and forgetfulness

الأربعون 39 — تجاوز الله عن أمتي الخطأ والنسيان

The hadith of Ibn Abbas that the Messenger of God ﷺ said: 'God has pardoned for my sake on behalf of my community error, forgetfulness, and what they were coerced into' — the thirty-ninth of al-Nawawi's Forty and of Ibn Rajab's commentary, graded hasan by al-Nawawi, narrated by Ibn Majah and al-Bayhaqi among others; Ibn Majah (2045), al-Uqayli, al-Tabarani and al-Bayhaqi transmit it through al-Awza'i from Ata' from Ibn Abbas, while Ibn Hibban, al-Daraqutni and others carry al-Awza'i from Ata' from Ubayd ibn Umayr from Ibn Abbas — an isnad sound in appearance whose narrators are all relied upon in the two Sahihs, and al-Hakim declared it sound on their condition; yet it has a hidden defect, for Imam Ahmad repudiated it vehemently, saying it is only transmitted from al-Hasan from the Prophet as a mursal, and when told that al-Walid ibn Muslim narrated its like from Malik from Nafi' from Ibn Umar he repudiated that too; and Abu Hatim al-Razi was presented with al-Awza'i's hadith, Malik's hadith, and al-Walid's route from Ibn Lahi'a from Musa ibn Wardan from Uqba ibn Amir (Jami' al-Ulum wal-Hikam pp. 796–809).
