1ـ مُحَمَّدُ بْنُ يَحْيَى وَغَيْرُهُ عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنْ فَضَالَةَ عَنِ الْحُسَيْنِ بْنِ عُثْمَانَ عَنْ سَمَاعَةَ عَنْ أَبِي بَصِيرٍ قَالَ
سَأَلْتُهُ عَنْ رَجُلٍ صَلَّى فَلَمْ يَدْرِ أَ فِي الثَّالِثَةِ هُوَ أَمْ فِي الرَّابِعَةِ قَالَ فَمَا ذَهَبَ وَهْمُهُ إِلَيْهِ إِنْ رَأَى أَنَّهُ فِي الثَّالِثَةِ وَفِي قَلْبِهِ مِنَ الرَّابِعَةِ شَيْءٌ سَلَّمَ بَيْنَهُ وَبَيْنَ نَفْسِهِ ثُمَّ يُصَلِّي رَكْعَتَيْنِ يَقْرَأُ فِيهِمَا بِفَاتِحَةِ الْكِتَابِ.
1. Muhammad ibn Yahya and others has narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from Fadalah from al-Husayn ibn ‘Uthman from Sama‘ah from abu Basir who has said the following:
“I once asked him (the Imam) 
, about a man who performs Salah (prayer) but does not know if he is in the third or fourth Rak‘at. He (the Imam) said, ‘It depends on what his guessing indicates. If he according to his guess thinks it is the third or fourth he accepts it along with his soul, then performs two Rak‘at in which he reads al-Fatihah al-Kitab only.”’
