The Chapter on the Virtues of Prayer
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 31
وَ رُوِيَ عَنِ اَلصَّادِقِ عَلَيْهِ اَلسَّلاَمُ: «صَلاَةٌ فَرِيضَةٌ خَيْرٌ مِنْ عِشْرِينَ حَجَّةً وَ حَجَّةٌ خَيْرٌ مِنْ بَيْتٍ مَمْلُوءٍ ذَهَباً يُتَصَدَّقُ مِنْهُ حَتَّى يَفْنَى.
It has been narrated from Imam Jafar ibn Muhammad Al-Sadiq عليه السلام: "An obligatory prayer (fardh) is better than twenty pilgrimages (Hajj), and one Hajj is better than a house filled with gold given in charity until it is depleted."
