Masruq narrates: Sayyiduna Abdullah (may Allah be pleased with him) led us in prayer when the sun had passed its zenith. I said to Sulayman: Is this the Zuhr prayer? He replied: Yes! Sayyiduna Abdullah (may Allah be pleased with him) said: By the One besides whom there is no god, this is the appointed time of this prayer.
Al-Tabarani recorded it in al-Mu'jam al-Kabir, and its narrators are thiqat (trustworthy).
