[Machine] The Messenger of Allah ﷺ used to say Takbeer (Allahu Akbar) whenever he lowered and raised himself (in prayer). He continued to do this until he met Allah (ﷻ) while still observing this practice. This last statement has been narrated in the continuous hadith from Ibn Shihab, from Abu Bakr ibn Abdur Rahman, and from Abu Salamah, from Abu Huraira (may Allah be pleased with them all).  

كَانَ رَسُولُ اللهِ ﷺ يُكَبِّرُ كُلَّمَا خَفَضَ وَرَفَعَ قَالَ فَلَمْ تَزَلْ تِلْكَ صَلَاتَهُ حَتَّى لَقِيَ اللهَ ﷻ وَهُوَ مُرْسَلٌ حَسَنٌ وَهَذِهِ اللَّفْظَةُ الْأَخِيرَةُ قَدْ رُوِيَتْ فِي الْحَدِيثِ الْمَوْصُولِ عَنِ ابْنِ شِهَابٍ عَنْ أَبِي بَكْرِ بْنِ عَبْدِ الرَّحْمَنِ وَأَبِي سَلَمَةَ عَنْ أَبِي هُرَيْرَةَ ؓ
