I said: if his ḥadīth is not good in itself, it is at least good due to others, because of Maṭar al-Warrāq's corroboration of it. The last sentence was narrated by Ayyūb from ʿAmr ibn Shuʿayb with the wording: "It is not permissible to combine a loan and a sale, nor two conditions in a sale, nor sell what you do not possess." It was recorded by al-Nasāʾī (2/225).

- "There is no impurity on water." It was narrated by Ibn Saʿd (8/137) and Aḥmad (6/330) from Sharīk from Simāk from ʿIkrimah from Ibn ʿAbbās from Maymūnah who said: I and the Messenger of Allāh became impure, so I washed from a basin, leaving some water, and the Prophet (ṣallá Allāhu ʿalayhi wa-sallam) came and washed from it. I said: I have washed from it, and he said: and mentioned it. I said: This isnād has trustworthy men, except that Sharīk - who is Ibn ʿAbdullāh al-Qāḍī - has poor memory, and he was inconsistent in his isnād. He narrated it once like this, making it from the musnad of Maymūnah herself, and another time he said: "from Ibn ʿAbbās who said: The Prophet (ṣallá Allāhu ʿalayhi wa-sallam) and Maymūnah became impure, so Maymūnah washed in a basin..." It was recorded by Aḥmad (1/337). So he made it from the musnad of Ibn ʿAbbās, not Maymūnah, and this is correct due to the corroboration by Sufyān and Abū al-Aḥwaṣ, as narrated by Abū Dāwūd and others, as is extracted in "Ṣaḥīḥ Abī Dāwūd" (61). Al-Dāraqutnī narrated (p. 42) from Abū ʿUmar al-Māzinī Ḥafṣ ibn ʿUmar who reported from Salīm ibn Ḥayyān from Saʿīd ibn Mināʾ from Jābir ibn ʿAbdullāh in a marfūʿ form and added: "Nor is there impurity on the earth, nor on the garment."
