Imam al-Redha (asws)

حدثنا أبو علي محمد بن أحمد بن محمد بن يحيى المعاذي النيسابوري قال: حدثنا أبو الحسن علي بن أحمد بن علي البصري المعدل قال: رأى رجل من الصالحين فيما يرى النائم رسول الله (ص) فقال: يا رسول الله من أزور من اولادك؟ فقال: إن من أولادي من اتاني مسموما وإن من أولادي من أتاني مقتولا، قال: فقلت له فمن أزور منهم يا رسول الله مع تشتت مشاهدهم أو قال أماكنهم؟ قال: من هو أقرب منك يعني بالمجاورة وهو مدفون بأرض الغربة قال: فقلت يا رسول الله تعني الرضا عليه السلام؟ فقال (ص): قل: صلى الله عليه قل صلى الله عليه ثلاثا


A good person (صالح) saw the Prophet (saww) in his dream. He asked the Prophet (saww) , "O Prophet (saww) Which one from your offspring should I go to visit?"

The Prophet (saww) said، "A few of my descendants who have come to me have been poisoned & a few of my offspring who have come to be have been killed"

Then he asked the Prophet (saww),  "O Prophet! Given the great distances between their shrines (or locations), which one of them shall I visit?"

The Prophet (saww) said, "Visit the one who is closest to you - that is whom you are near to and is buried in the land of loneliness."

Then he asked the Prophet (saww), "O Prophet (saww)! Do you mean Ar-Ridha (as)"?

The Prophet (saww) said, "Say: Allah's Blessings be upon him. Say: Allah's Blessings be upon him. Say: Allah's Blessings be upon him ... three times"


[Note: The last statement of the Prophet indicates that we should say "Blessings be upon him" when taking the name of the Imam's (as)
