Narrated `Aisha: The Prophet used to say in his bowing and prostrations, "Subhanaka l-lahumma Rabbana wa bihamdika; Allahumma ghfir li.' (Exalted [from unbecoming attributes] Are you O Allah our Lord, and by Your praise [do I exalt you]. O Allah! Forgive me).

Narrated Abu Huraira: When the Prophet said, "Sami`a l-lahu liman hamidah," (Allah heard those who sent praises to Him), he would say, "Rabbana wa laka l-hamd." On bowing and raising his head from it the Prophet used to say Takbir. He also used to say Takbir on rising after the two prostrations. (See Hadith No. 656).

Narrated Abu Huraira: Allah's Apostle said, "When the Imam says, "Sami`a l-lahu liman hamidah," you should say, "Allahumma Rabbana laka l-hamd." And if the saying of any one of you coincides with that of the angels, all his past sins will be forgiven."

Narrated Abu Salama: Abu Hurairah said, "No doubt, my Salat is similar to that of the Prophet (saws)." Abu Hurairah used to recite Qunut after saying Sami' Allahu liman hamida in the last Rak'a of the Zuhr, Isha and Fajr Prayers. He would ask Allah's Forgiveness for the true believers and curse the disbelievers.

Narrated Anas: The qunut [supplication before going down for prostration] used to be recited in the Maghrib and the Fajr prayers.

Narrated Rifa`a bin Rafi` Az-Zuraqi: One day we were praying behind the Prophet. When he raised his head from bowing, he said, "Sami`a l-lahu liman hamidah." A man behind him said, "Rabbana wa laka l-hamdu, hamdan kathiran taiyiban mubarakan fihi" (O our Lord! All the praises are for You, many good and blessed praises). When the Prophet completed the prayer, he asked, "Who has said these words?" The man replied, "I." The Prophet said, "I saw over thirty angels competing to write it first." Prophet rose (from bowing) and stood straight till all the vertebrae of his spinal column came to a natural position.

Narrated Thabit: Anas used to demonstrate to us the prayer of the Prophet and while demonstrating, he used to raise his head from bowing and stand so long that we would say that he had forgotten (the prostration).

Narrated Al-Bara': The bowing, the prostrations, the period of standing after bowing and the interval between the two prostrations of the Prophet used to be equal in duration .

Narrated Aiyub: Abu Qilaba said, "Malik bin Huwairith used to demonstrate to us the prayer of the Prophet at times other than that of the compulsory prayers. So (once) he stood up for prayer and performed a perfect Qiyam (standing and reciting from the Holy Qur'an) and then bowed and performed bowing perfectly; then he raised his head and stood straight for a while." Abu Qilaba added, "Malik bin Huwairith in that demonstration prayed like this Sheikh of ours, Abu Yazid." Abu, Yazid used to sit (for a while) on raising his head from the second prostration before getting up.
