7. Al-Husayn ibn Ahmad ibn Idris said on the authority of his father, on the authority of Ahmad ibn Ishaq that I wrote to Abu al-Hasan the third (al-Naqi) asking about the vision of (Allah) and what people say about it. Hence, he wrote:

Vision is only possible so long so there is no obstacle between the seer and the seen. So, when there is an obstacle to vision, or lack of light between the seer and the seen, vision is impeded or inaccurate. Fault necessitates when the seer equals the seen in the cause that is required between them for vision. When it comes to vision, we can speak in anthropomorphic terms due to cause and effect.
