[Machine] It is narrated that the Prophet ﷺ performed four or five raka'at (units of prayer) for Dhuhr or Asr prayers, then he made the two prostrations of forgetfulness. After that, the Messenger of Allah ﷺ said, "These two prostrations are for anyone who thinks that they have added or subtracted something from their prayer."
أَنَّ النَّبِيَّ ﷺ صَلَّى الظُّهْرَ أَوَ الْعَصْرَ خَمْسًا ثُمَّ سَجَدَ سَجْدَتَيِ السَّهْوِ ثُمَّ قَالَ رَسُولُ اللهِ ﷺ «هَاتَانِ السَّجْدَتَانِ لِمَنْ ظَنَّ أَنَّهُ زَادَ مِنْكُمْ أَوَ نَقَصَ»
