Musnad Abu Ya'la al-Mawsili 115:124

Abu Khaythama narrated to us, Yahya narrated to us, from Ibn Abi Arubah, from Qatadah, from Anas, that the Messenger of Allah (may Allah bless him and grant him peace) said: "What is the matter with people who raise their eyes toward the sky?" And he intensified his speech regarding that, and said: "They must cease from that, or their sight will be snatched away."
