The first thing that man will be asked about when he stands before Allah, Exalted be His Grandeur, is the obligatory prayers, the obligatory alms-tax (zakat), the obligatory fasting, the obligatory pilgrimage (hajj), and our guardianship (wilaya), the people of the Household. If he attests to our guardianship and dies believing that, his prayer, fasting, alms and pilgrimage will all be accepted.'
