He said, "I recited 'By the Star' [Najm 53:1] before the Prophet ﷺ, and he did not perform a prostration in it."
قال قرأت على النبي ﷺ {والنجم} فلم يسجد فيها.
Bukhari narrated it in the Book of Prostration for Quran Recitation (1072), and Muslim narrated it in the Book of Mosques (577), both from the hadith of Ismail bin Jafar, who said, "Yazid bin Khusayfa informed us, from Ibn Qusayt, from Ata bin Yasar, from Zayd bin Thabit," and he related it.This is evidence that prostration for recitation is not obligatory, and this is the view of Shafii and Ahmad.
