7. Qāsim ibn Muḥammad ibn ‘Ali narrated to me from his father, from his grandfather, from ‘Abdillāh ibn Ḥammād Al-Ansāri, from ‘Abdillāh ibn Sinān, who said: Abū ‘Abdillāh (Imam Sādiq ) said: Those who go to (the Ziyārah of) the grave of Ḥusain knowing his rights will be forgiven for all of their past and future sins.
