Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him) narrates this saying of the Prophet (peace and blessings be upon him): "On the Day of Resurrection the womb (that is, kinship) will be set up with a hooked form like the hook of a spindle, and it will speak with a sharp, eloquent tongue. It will join whoever kept it joined and cut off whoever cut it off."
Ahmad and al-Tabarani recorded it. The narrators of Ahmad are the narrators of the Sahih, except for Abu Thumamah al-Thaqafi, whom Ibn Hibban declared thiqah (trustworthy).
