H 82 - Like the incident of the Imam with Hababa Walibiyya, owner of the pebble on which Amirul Momineen (a.s) placed his seal and said to her: One who places a seal on this pebble is an Imam. Hababa survived till the Imamate of Imam Ridha (a.s). The Imam placed the seal on that pebble and Hababa witnessed the placing of seals by respected ancestors of Imam Ridha (a.s) and Imam Ridha (a.s) was the last Imam Hababa met. Hababa passed away after meeting Imam Ridha (a.s) and the Imam gave his own shirt to serve as her shroud.
