Sayyiduna Zayd bin Thabit (may Allah be pleased with him) narrated: The Prophet (peace and blessings be upon him) was dictating this verse to me: "We created man from an extract of clay." He recited the verse up to: "Then We brought him forth as another creation." Sayyiduna Mu'adh said to him: "Blessed is Allah Almighty, the best of creators." The Prophet (peace and blessings be upon him) laughed. Sayyiduna Mu'adh (may Allah be pleased with him) said to him: "O Messenger of Allah! What did you laugh at?" The Prophet (peace and blessings be upon him) said: "The verse ends with these words: 'So blessed is Allah Almighty, the best of creators.'"
Tabarani recorded it in al-Mu'jam al-Awsat; its chain contains Jabir al-Ju'fi, who is da'if (weak), though he has been declared trustworthy; the rest of its narrators are the narrators of the Sahih.
