عَنِ الرِّضَا (ع) قَالَ: مَا رَأََيْتُ َشَيْئاً أَسْرَعَ غِنًّى وَ لاَ أَنْفى لِلْفَقْرِ مِنْ إِدْمَانُ الْحَجِّ.
It has been narrated from al-Ridha [Imam ‘Ali Ibn Musa] (peace be upon him) that he said, “I have not seen a single thing which makes a person free from want (financially secure) quicker, nor which is more effective in removing poverty, than continuously performing the Hajj (year after year).”
