Muḥammad b. Mūsā رحمه الله narrated to me, saying that ʿAbd Allāh b. Jaʿfar al-Ḥimyarī narrated to him, from Muḥammad b. al-Ḥusayn b. Abī’l-Khaṭṭāb, from al-Ḥasan b. Maḥbūb, from Hishām b. Sālim, from ʿAmmār al-Sābāṭī, from Abī ʿAbd Allāh عليه السلام, who said: “The first of what will be asked of the servant when he is brought before Allāh عز وجل is concerning his obligatory prayers, and about his defraying the alms-tax, and about the obligatory fasts, and the pilgrimage, and about our guardianship—for we are the People of the House—and so if he affirmed our guardianship and died upon it, then his prayers, his fasts, his defrayment of alms-tax, and his pilgrimages will be accepted. And if he had not affirmed our guardianship before Allāh عز وجل, then not a single thing of his deeds will be accepted.”
