It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that when the Messenger of Allah (peace and blessings be upon him) began the prayer, he would raise both hands level with the shoulders, and when he raised his head from bowing (ruku‘), he would also raise both hands in the same way and say: «سَمِعَ اللّٰهُ لِمَنْ حَمِدَهُ رَبَّنَا وَ لَكَ الْحَمْدُ» . And between the prostrations, he would not raise his hands, nor when going into prostration.

It is narrated from Hazrat Zain ul Abideen, whose blessed name is Ali and he is the son of Sayyiduna Husain bin Ali bin Abi Talib (may Allah be pleased with them), that the Messenger of Allah (peace and blessings be upon him) used to say the takbeer in prayer when bowing and when rising, and his prayer always remained in this manner, until he met Allah, Glorious is His Majesty.

It is narrated from Sulayman bin Yasar that the Messenger of Allah, peace and blessings be upon him, used to raise his hands in prayer.

It is narrated from Sayyiduna Abu Salamah (may Allah be pleased with him) that Sayyiduna Abu Hurairah (may Allah be pleased with him) used to lead the prayer. He would say the takbeer when bowing and when rising, and then when he finished, he said: By Allah! Among all of you, I am the most similar to the prayer of the Messenger of Allah (peace and blessings of Allah be upon him).

It is narrated from Hazrat Salim bin Abdullah that Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) used to say the takbeer when bowing and rising in prayer.

Yahya narrated to me from Imam Malik, from Nafi', that Abdullah ibn Umar, may Allah be pleased with them both, when he began the prayer, he would raise both his hands level with his shoulders, and when he raised his head from bowing (ruku'), he would raise both his hands a little less than that.

Abu Nu'aym Wahb bin Kaysan narrates that Sayyiduna Jabir bin Abdullah Ansari (may Allah be pleased with both of them) used to teach them the takbir in prayer, so he would instruct them to say the takbir when we bow and when we rise.

Ibn Shihab used to say that when a person catches the bowing (ruku) and says the takbir, then this takbir will suffice for the opening takbir (takbir al-tahrima).

Imam Malik, may Allah have mercy on him, said: In our view, it is sufficient that with this takbir, one intends the Takbir al-Tahrimah.

Imam Malik, may Allah have mercy on him, was asked about a person who joined the prayer with the Imam and forgot the Takbir al-Tahrimah and the Takbir for bowing, until he completed one rak'ah, then remembered that he had not said the Takbir al-Tahrimah, nor the Takbir at the time of bowing, but said the Takbir in the second rak'ah. Imam Malik, may Allah have mercy on him, replied that it is better for him to repeat the prayer from the beginning. And as for the one who forgot to say the Takbir al-Tahrimah with the Imam but said the Takbir al-Tahrimah at the time of bowing, then this Takbir will suffice for the Takbir al-Tahrimah, provided that he intended with this Takbir the Takbir al-Tahrimah.
