Is it permissible to seek blessing from the righteous?

Question : If someone were to argue that the Companions sought blessing from the Prophet (peace and blessings be upon him), and then said to the Jews, "Now seek blessing from the Prophet (peace and blessings be upon him)."

Answer : Do we seek blessing? He says: This is not correct. I do not understand this from the Companions. The Companions did not seek blessing from Abu Bakr, nor from 'Umar, nor from any of the other Companions.
