قُلْتُ لَهُ مَنْ لَمْ يَدْرِ فِي أَرْبَعٍ هُوَ أَمْ فِي ثِنْتَيْنِ وَ قَدْ أَحْرَزَ الثِّنْتَيْنِ قَالَ يَرْكَعُ رَكْعَتَيْنِ وَ أَرْبَعَ سَجَدَاتٍ وَ هُوَ قَائِمٌ بِفَاتِحَةِ الْكِتَابِ وَ يَتَشَهَّدُ وَ لَا شَيْءَ عَلَيْهِ وَ إِذَا لَمْ يَدْرِ فِي ثَلَاثٍ هُوَ أَوْ فِي أَرْبَعٍ وَ قَدْ أَحْرَزَ الثَّلَاثَ قَامَ فَأَضَافَ إِلَيْهَا أُخْرَى وَ لَا شَيْءَ عَلَيْهِ وَ لَا يَنْقُضُ الْيَقِينَ بِالشَّكِّ وَ لَا يُدْخِلُ الشَّكَّ فِي الْيَقِينِ وَ لَا يَخْلِطُ أَحَدَهُمَا بِالْآخَرِ وَ لَكِنَّهُ يَنْقُضُ الشَّكَّ بِالْيَقِينِ وَ يُتِمُّ عَلَى الْيَقِينِ فَيَبْنِي عَلَيْهِ وَ لَا يَعْتَدُّ بِالشَّكِّ فِي حَالٍ مِنَ الْحَالَاتِ .
Translation
Ali Bin Ibrahim, from his father and Muhammad Bin Ismail, from Al Fazl Bin Shazaan, altogether from Hammad Bin Isa, from Hareyz, from Zurara, (It has been narrated) from one of the two (5<sup>th</sup> or 6<sup>th</sup> Imam<sup>asws</sup>), said, ‘I said to him<sup>asws</sup>, ‘The one who does not know whether he is in a fourth or in the second, and he has accomplished two’. He<sup>asws</sup> said: ‘He should perform two <span class="iTxt">Rak’at</span> and four <span class="iTxt">Sajdah</span>s while he is standing, with the Opening of the Book (Chapter 1), and he should perform <span class="iTxt">Tashahhud</span> and there would be nothing upon him; and when he does not know whether he was in a third or in a fourth (<span class="iTxt">Rak’at</span>), and he has accomplished three, he would stand and increase upon it by another, and there would be nothing upon him. And neither can the conviction be invalidated by the doubt nor can the doubt enter into the conviction, nor can one of the two get mixed up with the other, but, the doubt would be invalidated by the conviction, and he would complete (the <span class="iTxt">Salāt</span>) upon the conviction. Thus, he would build upon it and he would not repeat with the doubt in any state from the states’.
