٤ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنْ عُثْمَانَ بْنِ عِيسَى عَنْ سَمَاعَةَ قَالَ قَالَ مَنْ حَفِظَ سَهْوَهُ وَأَتَمَّهُ فَلَيْسَ عَلَيْهِ سَجْدَتَا السَّهْوِ إِنَّمَا السَّهْوُ عَلَى مَنْ لَمْ يَدْرِ زَادَ أَمْ نَقَصَ مِنْهَا.
4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from ‘Uthman ibn ‘Isa from Sama‘ah who has said the following: “He (the Imam) , has said, ‘If one knows the kind of mistake he has made and completes it then Sajdah (prostration) for mistake is not necessary for him. Sajdah (prostration) for mistake is upon one who does not know if he has increased or decreased something in Salah (prayer).”’
