What is the ruling on performing the prostration of recitation (Sujood al-Tilawah) during the sermon (Khutbah)?

Primary text

If the verse requiring prostration is recited during the sermon, the reciter has the choice to descend and perform the prostration. If it is possible to prostrate upon the pulpit (Minbar), the prostration should be performed there. If the prostration is omitted, there is no blame. This position is supported by the actions of Umar, who both performed and omitted it, and this is the view of Al-Shafi'i. Umar, Abu Musa, Ammar, Al-Nu'man ibn Bashir, and Uqbah ibn 'Amir also omitted it. The rationale is that since the cause (the recitation) arose, and performing the prostration does not cause a lengthy break, it is recommended to perform it, analogous to praising Allah upon sneezing and responding to the sneezer. However, it is not obligatory because the prostration of recitation is not mandatory.
