Abu al-Hasan [al-Ridha] عليه السلام stood at the place of Bani Zurayq [in Madina] and said to me whilst having raised his voice: O Ahmad, I said: at your service, he said: when the messenger of Allah صلى الله عليه وآله وسلم passed away the people strove to extinguish the light of Allah but Allah refused anything but to perfect His light through the Commander of the Faithful عليه السلام. Similarly, when Abu al-Hasan [al-Kadhim] عليه السلام passed away Ali b. Abi Hamza and his fellows strove to extinguish the light of Allah but Allah refused anything but to perfect His light. When a person joins the people of truth they get delighted because of him, but when he leaves them they do not feel sad because of him [leaving], that is because they are sure of their affair [the truth of their religion], however, when a person joins the people of falsehood they get delighted because of him, and when he leaves them they are grieved because of him, that is because they are in doubt about their affair. Allah Majestic is His Majesty says: “an enduring abode and a place of temporary lodging” (6:98), then he [the Imam] said: Abu Abdillah عليه السلام said: the enduring abode is the established [constant faith] while the temporary lodging is the rented out [faith which will not last].
