Sayyiduna Abu Hurayrah (may Allah be pleased with him) said: "When the children of Abu al-As reach thirty, the religion of Allah Almighty will be meddled with, the wealth of Allah Almighty will become personal property, and the servants of Allah Almighty will become slaves."
Abu Ya'la recorded it as a narration of Isma'il, which he narrated from Ibn Ajlan; he did not give Isma'il's lineage, and I do not know Isma'il. The rest of the narrators of this report are the narrators of the Sahih.
