Arabic (Original)
حَدَّثَنَا رَوْحُ بْنُ عُبَادَةَ حَدَّثَنَا ابْنُ جُرَيْجٍ أَخْبَرَنِي مُحَمَّدُ بْنُ يُوسُفَ مَوْلَى عَمْرِو بْنِ عُثْمَانَ عَنْ أَبِيهِ عَنْ مُعَاوِيَةَ بْنِ أَبِي سُفْيَانَ أَنَّهُ سَمِعَ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ مَنْ نَسِيَ شَيْئًا مِنْ صَلَاتِهِ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ.
English Translation
Rawh ibn 'Ubada narrated to us: Ibn Jurayj narrated to us: Muhammad ibn Yusuf, the freedman of 'Amr ibn 'Uthman, informed me from his father from Mu'awiya ibn Abi Sufyan: that he heard the Messenger of Allah, peace and blessings be upon him, say: 'Whoever forgets something of his prayer, let him prostrate two prostrations while seated.'
