 Ibn Ubayy followed suit, according to Maxime Rodinson, as "he thought it wiser to join than to stand out against it".However, Rudi Paret thinks it probable that he converted very soon after the Hijra, at the same time as Sa'd ibn Mua'dh.Islamic tradition, which views Ibn Ubayy's conversion as insincere, labelled him "leader of the hypocrites" ("munafiqun").
