Imam Jaffer al-Sadiq (as)
O’ Rufa’ah! a person does not have faith in Allah (swt), Muhammad (sa) or in Ali (as), if they do not receive their faithful brother (in faith) who is having problems, with open arms. In such a case, if that person is able to solve the problem of their brother (in faith), they should instantly take urgent action and if not, they must ask others for help so that the problem of their faithful brother is solved. If someone does not do as I have described, there would be no relation of guardianship between us and them.
