قَالَ لِي أَ تَدْرِي لِمَ جُعِلَ الذِّرَاعُ وَ الذِّرَاعَانِ قَالَ قُلْتُ لِمَ قَالَ لِمَكَانِ الْفَرِيضَةِ لَكَ أَنْ تَتَنَفَّلَ مِنْ زَوَالِ الشَّمْسِ إِلَى أَنْ يَبْلُغَ ذِرَاعاً فَإِذَا بَلَغَ ذِرَاعاً بَدَأْتَ بِالْفَرِيضَةِ وَ تَرَكْتَ النَّافِلَةَ .
Translation
Al Husayn Bin Muhammad Al Ashary, from Abdullah Bin Aamir, from Ali Bin Mahziyar, from Fazalat in Ayoub, from Al Husayn Bin Usman, from Ibn Muskan, from Zurara who said, ‘He<sup>asws</sup> said to me: ‘Do you know why a cubit and two cubits have been made to be?’ I said, ‘Why?’ He<sup>asws</sup> said: ‘In place of the Obligatory (<span class="iTxt">Salāt</span>). It is for you that you can pray Optional (<span class="iTxt">Salāts</span>) from the (start of the) decline of the sun up it (the shadow) reaching one cubit. So when it reaches to one cubit, begin with the Obligatory and leave the Optional’.
