And the explanation of the evidence that the worshipper will perform these two prostrations after saying the salutation, not before.

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) led us in one of the two afternoon prayers. After performing two rak‘ahs, he said the salam. Then the Messenger of Allah (peace and blessings be upon him) came to a piece of wood lying crosswise in the mosque (towards the qiblah) and leaned on it with both his hands, as if he was very angry. The narrator says that, during this time, the hasty people left through the doors of the mosque and began to say to each other that the prayer had been shortened. Among the people were Sayyiduna Abu Bakr (may Allah be pleased with him) and Sayyiduna Umar (may Allah be pleased with him), but they too were afraid to speak to the Messenger of Allah (peace and blessings be upon him). Among the people was a man with long arms, who was called Dhu’l-Yadayn. He said,“O Messenger of Allah, did you forget or has the prayer been shortened?”The Messenger of Allah (peace and blessings be upon him) said,“I did not forget, nor has the prayer been shortened.”Then the Messenger of Allah (peace and blessings be upon him) asked the people,“Is Dhu’l-Yadayn speaking the truth?”The Companions replied,“Yes.”The narrator says that the Messenger of Allah (peace and blessings be upon him) came and performed the missed prayer, then said the salam, then said“Allahu Akbar”and performed a prostration like his usual prostration or even longer. Then the Messenger of Allah (peace and blessings be upon him) raised his blessed head, then said“Allahu Akbar”and performed a prostration like his usual prostration or even longer. Then the Messenger of Allah (peace and blessings be upon him) raised his blessed head and said“Allahu Akbar.”(Ibn ‘Awn) the narrator says that sometimes the students would say (to Ibn Sirin),“Then the Messenger of Allah (peace and blessings be upon him) said the salam,”so (Ibn Sirin) said,“I have been informed by Sayyiduna ‘Imran ibn Husayn (may Allah be pleased with him) that he said in his narration: ‘Then the Messenger of Allah (peace and blessings be upon him) said the salam.’”(These words are not in the above narration of Sayyiduna Abu Hurairah (may Allah be pleased with him), so Ibn Sirin mentioned these words from ‘Imran at the students’ inquiry.) These are the words of the narration of San‘ani.
