In the story of Dhu al-Yadayn, it is narrated from Abu Hurayrah (may Allah be pleased with him) that he (peace and blessings be upon him) said the takbir and prostrated. Hisham bin Hassan states that he said the takbir twice and then prostrated.
(b) Hammad bin Zayd is alone in narrating this hadith from Hisham, and all the narrators narrate it from Ibn Sirin. Then all the narrators narrate it from Hisham bin Hassan, but they did not mention the first takbir; Hammad bin Zayd alone mentioned it.
