حَدَّثَنَا عَبْدُ اللَّهِ بْنُ الْوَلِيدِ حَدَّثَنَا سُفْيَانُ حَدَّثَنَا جَابِرٌ عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْأَسْوَدِ عَنْ الْأَسْوَدِ عَنْ عَبْدِ اللَّهِ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ صَلَّى الظُّهْرَ أَوْ الْعَصْرَ خَمْسًا ثُمَّ سَجَدَ سَجْدَتَيْنِ فَقَالَ هَذِهِ السَّجْدَتَانِ لِمَنْ ظَنَّ مِنْكُمْ أَنَّهُ زَادَ أَوْ نَقَصَ
مسند امام احمد بن حنبل · Hadith 4072
It was narrated from 'Abdullah (RA) that the Prophet prayed Zuhr or 'Asr with five rak'ahs, then he did the two prostrations of forgetfulness. Then the Messenger of Allah (PBUH) said: "These two prostrations are for anyone among you who thinks that he did more or less."
