Hadith
Imam Reza (a.s) said:
 ومَا في ذلِكَ لجَمِيعِ الخَلقِ مِن المَنافِعِ... ومَنفَعةِ مَن في المَشرِقِ والمَغرِبِ ومَن في البَرِّ والبَحرِ ممَّن يحِجُّ وممِّن لا يحِجُّ من تاجِرٍ وجالبٍ وبائعٍ ومُشتَرٍ وكاسِبٍ ومِسكينٍ وقَضاءِ حوائِجِ أهلِ الأطراف
The benefits of Hajj cover both east and west; those who perform the Hajj rites and those who do not whether they are businessmen, shopkeepers, or poor. People from all classes of societies are blessed with the benefits of Hajj.See Elal ush-Shara'ie; vol. 2 p.90 Hadith 5
