Allah (may He be glorified and exalted) has instructed us, in the Holy Qur’an, to pray in general terms. The Messenger of Allah (blessings and peace of Allah be upon him) explained it to us very clearly in word and deed,and the Sahabah (may Allah be pleased with them) transmitted that from the Messenger of Allah (blessings and peace of Allah be upon him) in great detail. So there is no room to add or subtract anything. In this hadith, Abu Hurayrah (may Allah be pleased with him) narrates part of the description of the Prophet’s prayer, telling us that when the Messenger of Allah (blessings and peace of Allah be upon him) stood to pray, he said takbir when he began the prayer, which is known as takbirat al-ihram (opening takbir). Then he said takbir when he began to move to the bowing posture, when he prostrated, when he lifted his head from prostration, when he prostrated a second time, when he lifted his head again, and when he stood up following the first two rak‘ahs, after sitting to recite the first tashahhud. Then he would do that throughout the prayer, until he finished it. And he would say when he stood up straight after bowing: Sami‘a Allahu limanhamidah(Allah hears those who praise Him), then he would say once he was standing up straight: Rabbanalaka al-hamd. This indicates that the imam who is leading the prayer should recite both the tasmi‘ (Sami‘a Allahu limanhamidah) and the tahmid (Rabbanalaka al-hamd); and that the tasmi‘ is the dhikr to be said when rising from bowing, and the tahmid is the dhikr to be said when one has stood upright. This hadith indicates that it is prescribed to say takbir with every movement up and down, except when rising from bowing, when one should say “Sami‘a Allahu limanhamidah; Rabbanalaka al-hamd.”.
