Sayyidah Maymunah (may Allah be pleased with her), the wife of the Prophet (peace and blessings be upon him), narrates: I heard the Prophet (peace and blessings be upon him) say: "My Ummah will continue upon goodness as long as children born of fornication do not become widespread among them; when children born of fornication become widespread among them, Allah Almighty will soon envelop them all in punishment."
Ahmad, Abu Ya'la and al-Tabarani recorded it. He (al-Tabarani) recorded these words: "My Ummah will continue upon goodness, holding firmly to its affairs, as long as (children born of fornication) do not appear (among them)." Its chain contains Muhammad bin Abd al-Rahman bin Labibah, whom Ibn Hibban declared thiqah (trustworthy) and Yahya bin Ma'in declared da'if (weak); and Muhammad bin Ishaq has explicitly stated that he heard it directly, so the hadith is sahih (authentic) or hasan (good).
