Musannaf Ibn Abi Shaybah 32030 — When something in the Quran

Abdullah bin Salamah said: Sayyiduna Mu'adh (may Allah be pleased with him) said: "As for the Qur'an, it too has clear markers, just as a road has markers, which are hidden from no one. So whatever of it you understand, do not ask anyone further about it, and whatever causes you doubt, entrust it to one who has knowledge."
