The Source of Traditions on Imam al-Riḍā (Vol 2) · Hadith 554 (#Ḥadīth #1)

1- حَدَّثَنا أَحمَد بن زياد بن جَعفَر الهمداني رَضِىَ اللهُ عَنْهُ قالَ حَدَّثَنا عَلِيٍّ بن إِبراهِيم بن هاشِمٍ عَن أبِيهِ عَن ياسر الخادم قالَ قالَ عَلِيٍّ بن مُوسَى الرِّضا لا تُشَدُّ الرِّحَالُ إِلَى شَيْءٍ مِنَ الْقُبُورِ إِلاّ إِلَى قُبُورِنَا أَلا وَإِنِّي مَقْتُولٌ بِالسَّمِّ ظُلْماً وَمَدْفُونٌ فِي مَوْضِعِ غُرْبَةٍ فَمَنْ شَدَّ رَحْلَهُ إِلَى زِيَارَتِي اسْتُجِيبَ دُعَاؤُهُ وَغُفِرَ لَهُ ذُنُوبُهُ.

1. Ahmad ibn Ziyad ibn Ja’far al-Hamadani narrated to us, saying: Ali ibn Ibrahim ibn Hashim narrated from his father, from Yasir al-Khadim, who said: Ali ibn Musa al-Ridha said, "Do not set out on a journey to visit any graves except for our graves. Know that I have been unjustly killed by poison and am buried in a strange land. Whoever embarks on a journey to visit me, his supplication will be answered, and his sins will be forgiven."
