Allamah Sayyid Hashim Bahrani has mentioned in the book of
Madinatul Maajiz that
they brought a blind child to Imam Sajjad (a.s.). Imam (a.s.) passed his hands over his eyes and he gained sight.
They brought a dumb man to the Imam and the latter asked him
to speak up and he began to speak.
A cripple was brought to Imam (a.s.). His Eminence passed his
hands over his legs and he stood up and was able to walk.
In the same way, he passed his blessed hands over Abu Khalid
Kabuli and showed Paradise to him.
