[Machine] We used to talk during prayer in the time of the Messenger of Allah ﷺ. One of us would speak to his companion about a need between them until the verse was revealed: "Guard the prayers and the middle prayer and stand before Allah in devotion." Then we were commanded to be silent.
كُنَّا عَلَى عَهْدِ رَسُولِ اللهِ ﷺ نَتَكَلَّمُ فِي الصَّلَاةِ يُكَلِّمُ أَحَدُنَا صَاحِبَهُ فِي الْحَاجَةِ فِيمَا بَيْنَهُ وَبَيْنَهُ حَتَّى نَزَلَتْ {حَافِظُوا عَلَى الصَّلَوَاتِ وَالصَّلَاةِ الْوُسْطَى وَقُومُوا لِلَّهِ قَانِتِينَ} فَأُمِرْنَا حِينَئِذٍ بِالسُّكُوتِ
