النضر عن إبراهيم بن عبد الحميد عن إسحاق بن غالب قال: سمعت أبا عبد الله عليه السلام يقول: في هذه الآية ج ولولا أن يكون الناس أمة واحدة لجعلنا لمن يكفر بالرحمن لبيوتهم سقفا من فضة ومعارج عليها يظهرون، قال: لو فعل لكفر الناس جميعا
7.Al-Naḍr narrated from Ibrāhīm ibn ʿAbd al-Ḥamīd, from Isḥāq ibn Ghālib who said, “I heard Abā ʿAbdillāh speaking about the following verse: Were it not that people might have become a single nation [of disbelievers], We would have given all those who disbelieve in the Compassionate [Lord] houses with roofs of silver, and sweeping stairways to ascend (Q43:33). He said, ‘If He did so all the people would be disbelievers.’”
