The following screenshot shows strong daleel (evidence) for doing Raf al-Yadain (raising the hands before going into Ruku and after rising from Ruku). This is all from Sahih Bukhari, which is the most authentic book after the Qur’aan and note that several hadiths have been reported by different narrators, which all support and compliment each other. We hope that this evidence was something you were looking for in order to provide clarity on the issue of Raf al-Yadain and to remove any doubts you had, insha’Allaah.
