19- حَدَّثَنا أَحمَد بن مُحَمَّد بن يحيى العطار قالَ حَدَّثَنا سعد بنعَبدُ اللَّه عَن أيوب بن نوح قالَ سَمِعتُ أبا جَعفَر مُحَمَّد بن عَلِيٍّ بن مُوسَى a.sُ يَقُولُ من زار قبر أبي a.sُ بطوس غَفَرَ الله لَهُ ما تُقَدِّم مَن ذَنبِه و ما تُأَخِّر فَإذا كانَ يَومَ القِيامَة نصب لَهُ مَنبر بِحذاء مِنبَر رَسُول الله صَلَّى اللهُ عَلَيْهِ وَآلِهِ حَتّى يُفَرِّغُ الله تَعالى مِن حِساب العِباد.

66-19 Ahmad ibn Muhammad ibn Yahya al-Attar narrated that Sa’d ibn Abdullah quoted on the authority of Ayyoub ibn Nooh, “I heard Aba Ja’far Muhammad ibn Ali ibn Musa (Imam Jawad) say, ‘God will forgive all the sins committed by whoever visits the shrine of my father (Imam Ridha’) in Toos. On the Resurrection Day, a pulpit will be set up for him in front of the pulpit of God’s Prophet (S) where he will be seated until God the Highest gets done with the Reckoning of His servants’ deeds.’”
