It is narrated from Sayyiduna Zayd bin Thabit (may Allah be pleased with him) that he said: "The Messenger of Allah (peace and blessings be upon him) dictated this verse to me: from 'And We certainly created man from an extract of clay' up to 'then We produced him as another creation'. Then Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him), (who was present there,) said: 'So blessed is Allah, the best of creators.' At this the Messenger of Allah (peace and blessings be upon him) smiled. Sayyiduna Mu'adh (may Allah be pleased with him) said: O Messenger of Allah (peace and blessings be upon him)! What made you smile? He (peace and blessings be upon him) said: 'It is with this very (phrase) that the verse ends: So blessed is Allah, the best of creators.'"
This hadith is not narrated from Sayyiduna Zayd bin Thabit (may Allah be pleased with him) except with this chain, and Adam bin Abi Iyas (may Allah have mercy on him) is alone in narrating it.
