Majma al-Zawaid — Hadith 11197

Sa'id bin Jubayr said: "And the one who took the greater part of it." This means: the major portion of it. "Among them." That is, one of the accusers; this is Ibn Ubayy, the leader of the hypocrites, and he is the one who said: "She is not free of him, and he is not free of her." "For him will be a great punishment." In this verse there is an instructive lesson for the Muslims: when an error occurs among the Muslims, whoever helps in that error by deed or word, or by putting it forward, or by liking it, or by being pleased with it, will be counted as sharing in that error according to the share of those taking part in it. And when an error occurs among the Muslims, whoever is present but dislikes it is like one who is absent, and whoever is absent yet is pleased with it is like one who is present.
Tabarani recorded it; its chain contains Ibn Lahi'ah, in whom there is weakness, though his hadith has been graded hasan (good); the rest of its narrators are the narrators of the Sahih.
