Musnad Abu Ya'la al-Mawsili 110:205

Hadba ibn Khalid narrated to us, Hammad ibn Salamah narrated to us, he said: Imran ibn Hudayr informed me, from Abdullah ibn Shaqiq, that Ibn Abbas delayed the Maghrib prayer one night. A man said to him, "The prayer." He remained silent. The man said to him, "The prayer." He said, "May you have no mother! Are you teaching us about the prayer? The Prophet, peace and blessings of Allah be upon him, would sometimes combine them in Medina."
