Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates that the Prophet (peace and blessings be upon him) said: "When the shadow is one and a half cubits to two cubits, then offer the Zuhr prayer."
Abu Ya'la recorded it. Its chain contains a narrator, Asram bin Hawshab, who is a kadhdhab (liar).
