وَ عَنْهُ عَنْ فَضَالَةَ عَنْ حُسَيْنٍ عَنِ اِبْنِ مُسْكَانَ عَنِ اَلْحَسَنِ بْنِ زِيَادٍ اَلصَّيْقَلِ قَالَ قَالَ لِي أَبُو عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ :«إِذَا صَلَّى اَلرَّجُلُ جَالِساً وَ هُوَ يَسْتَطِيعُ اَلْقِيَامَ فَلْيُضَعِّفْ»
And from him, from Fadalah, from Husayn, from Ibn Muskan, from al-Hasan ibn Ziyad al-Sayqal, who said:
Abu Abdillah عليه السلام said to me: "If a man prays while sitting and he is able to stand, then let him double (the prayer)."
