It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that this verse was recited in the presence of Sayyiduna Umar (may Allah be pleased with him): "Every time their skins are roasted through, We will replace them with other skins." Sayyiduna Umar (may Allah be pleased with him) said: "Recite it again." So the reciter recited it again, and Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) said: "I have its explanation: (the skins) will be replaced a hundred times in a single hour." Sayyiduna Umar (may Allah be pleased with him) said: "This is how I too heard it from the Messenger of Allah (peace and blessings be upon him)."
This hadith is not narrated from Sayyiduna Umar (may Allah be pleased with him) except with this chain, in which Hisham bin Ammar (may Allah have mercy on him) is alone.
