(a) It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) said 'Sami'allahu liman hamidah' (Allah has heard the one who praised Him), he would also say 'Allahumma rabbana lakal-hamd' (O Allah, our Lord, to You belongs all praise); when he bowed he said the takbir, when he raised his head he also said the takbir, and when he stood up from the two rak'ahs he said 'Allahu akbar' (Allah is the Greatest).
(b) From the word 'kana' (he used to) in this hadith it is understood that he (peace and blessings be upon him) always did this.
(c) In this hadith, the takbir when raising the head means that he (peace and blessings be upon him) said the takbir when, having raised his head from bowing, he went down towards prostration, and Allah knows best. This is explained in another hadith which Abu Bakr bin Abd al-Rahman narrates from Sayyiduna Abu Hurayrah (may Allah be pleased with him).
(d) It has been narrated from Sayyiduna Hudhayfah bin al-Yaman (may Allah be pleased with him) that he too prayed with the Messenger of Allah (peace and blessings be upon him). When he (peace and blessings be upon him) raised his head from bowing, he said 'Sami'allahu liman hamidah' (Allah has heard the one who praised Him), 'Allahumma rabbana lakal-hamd' (O Allah, our Lord, to You belongs all praise).
