When the Messenger of Allah (may Allah's peace and blessings be upon him) got up for prayer, he would say Takbīr when he stands. Then he would say Takbīr when he bows. Then he would say: "Allah hears the one who praised Him" when he raises his back from bowing

Explanation

Throughout prayer one glorifies Allah with words and actions. This noble Hadīth explains the emblem of prayer: Allah's grandeur and greatness. This was made its symbol only because prayer itself was prescribed for the exaltation and glorification of Allah. When starting the prayer, one says the Takbīr al-Ihrām while standing up. After one recites some Qur'an and bows, one says "Allah Akbar". Then when rising from bowing, one says ''Allah hears the one who praised Him!'' Then one stands up again, praises Allah and glorifies Him while standing. When going down for prostration, one says "Allah Akbar" and does so when rising one's head from prostration. The procedure is observed throughout the prayer, until one finishes. When standing up from the first Tashahhud, one says "Allah Akbar". In taking up a new posture in prayer, one says Takbīr except when rising from bowing.
