Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: "And the one who took upon himself the greater part of it" [Surah An-Nur: 11]: meaning spreading it and making it public. "From among them" [Surah An-Nur: 11]: meaning Abdullah bin Ubayy bin Salul. "Will have a great punishment" [Surah An-Nur: 11]: meaning in this world the punishment of lashes — the Messenger of Allah (peace and blessings be upon him) gave him eighty lashes — and in the Hereafter his abode is Hell.
