Majma al-Zawaid — Hadith 8999

Sayyiduna Ma'qil bin Yasar (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "After me, when only a short time has passed, injustice will come, and whenever injustice appears, an equal amount of justice will depart, until a child will be born in the time of injustice who will know nothing other than injustice. Then Allah Almighty will bring justice, and as justice comes, injustice will depart in the same measure, until a child will be born in the time of justice who will know nothing other than it (that is, nothing of injustice)."
Ahmad recorded it. Its chain contains Khalid bin Tahman, whom Abu Hatim al-Razi and Ibn Hibban declared thiqah (trustworthy); Ibn Hibban said: He makes mistakes and falls into errors. The rest of its narrators are thiqat (trustworthy).
