Completing the Prayer in al-'Aziziyah and the Prostration for Forgetfulness

The questioner:
We prayed the 'Asr prayer today in al-'Aziziyah at the home of one of the brothers, and one of the brothers from the people of Makkah led us in prayer. He shortened the prayer while we were in al-'Aziziyah, and he is from the people of Makkah and a pilgrim. After the prayer, I told him to complete the prayer because you are not in Mina. So he completed the prayer, then he performed the prostration for forgetfulness before the closing salam.

The Shaykh:
Good, that is good, because a resident of Makkah who comes from Makkah, from the pilgrims who arrived late on the fourth day or later, they shorten the prayer. It is mentioned in the rites, and he says in his second journey

The questioner:
A question from me: Is this prostration the prostration for forgetfulness, or is it not?

The Shaykh:
He had said the closing salam due to forgetfulness. As for if he said the closing salam out of ignorance, he does not write it down, but he completes the prayer and says the salam.
