Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Whoever strikes a single lash unjustly, retribution will be taken from him on the Day of Resurrection."
Imam al-Bazzar and Imam al-Tabarani in al-Mu'jam al-Awsat recorded it, and the chains of both are hasan (good).
