According to the Hanafi school, it is necessary (wajib) to prostrate for fourteen of the fifteen listed prostrations in the Qur’an. The second listed prostration in Surat al-Hajj is not considered a verse of prostration. [Shurunbulali, Maraqi al-Falah]
However, there is valid, scholarly disagreement on this matter between the schools.
And Allah alone gives success.
