1048. hadíth
وَقَالَ أَبُو بَصِيرٍ: قُلْتُ لِأَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ إِنَّا نَتَحَدَّثُ وَ نَقُولُ مَنْ صَلَّى وَ هُوَ جَالِسٌ مِنْ غَيْرِ عِلَّةٍ كَانَتْ صَلاَتُهُ رَكْعَتَيْنِ بِرَكْعَةٍ وَ سَجْدَتَيْنِ بِسَجْدَةٍ فَقَالَ «لَيْسَ هُوَ هَكَذَا هِيَ تَامَّةٌ لَكُمْ.
Abu Basir said: I said to Abu Ja'far (a.s), "We talk and say that whoever prays while sitting without any illness, his prayer consists of two rak'ahs in place of one, and two prostrations in place of one." Imam (a.s) said: "It is not as you say. It is complete for you."
