[Machine] The Messenger of Allah used to say the takbir (saying "Allahu Akbar") in every rukoo (bowing) and sujood (prostration), and during raising up and putting down (in prayer). Abu Bakr and Umar, may Allah be pleased with them, also used to say "Peace be upon you" and "May the mercy of Allah be upon you", using their right hands and their characteristics.
كَانَ رَسُولُ اللهِ يُكَبِّرُ فِي كُلِّ رُكُوعٍ وَسُجُودٍ وَرَفْعٍ وَوَضْعٍ وَأَبُو بَكْرٍ وَعُمَرُ رِضْوَانُ اللهِ عَلَيْهِمَا وَيُسَلِّمُونَ عَنْ أَيْمَانِهِمْ وَشَمَائِلِهِمْ السَّلَامُ عَلَيْكُمْ وَرَحْمَةُ اللهِ
