Hadith 66-8

و بهذا الإسناد عَن عَبد العَظيم بن عَبدُ اللَّه قالَ: قُلتُ لأبي جَعفَر عَلَيْهِ السَّلامُ قد تحيرت بين زيارة قبر أبي عَبدُ اللَّه‏ عَلَيْهِ السَّلامُ و بين زيارة قبر أبيك‏ عَلَيْهِ السَّلامُ بِطُوس فَمَا تَرَى فَقَالَ لِي مَكَانَك ثُمَّ دَخَلَ وَخَرَجَ وَدُمُوعُهُ تَسيِلُ عَلَى خَدَّيهِ فَقَالَ زُوّارُ قَبرِ أَبِي عَبْدِ الله‏ عَلَيْهِ السَّلامُ كَثِيرُون و زُوّارُ قَبرِ أَبِي‏ عَلَيْهِ السَّلامُ بِطُوس قَلِيلُون

There is another tradition through the same chain of documentation in which Abdul Adheem ibn Abdullah has said that he asked Abi Ja’far (al-Jawad) (a.s.), “I wonder whether I should go on a pilgrimage to the shrine of Abi Abdullah (Imam Husayn) (a.s.) or go on a pilgrimage to the shrine of your father (a.s.) in Toos. What do you think?” Then Abi Ja’far (a.s.) told him, “Wait a little and stay here until I come back.” Then the Imam (a.s.) went inside the house and came back with eyes filled with tears and said, “There are many people who visit the shrine of Abi Abdullah Imam Al-Husayn (a.s.). However, there are only a few who visit the shrine of my father (a.s.) in Toos.”
