Musnad Abu Ya'la al-Mawsili 152:158

Abu Khaythama narrated to us, Ibn Idris narrated to us, he said: I heard al-A’mash mentioning from Shaqiq, who said: ‘Abdullah used to come out to us and say: “I am indeed informed of your location, and nothing prevents me from coming out to you except the dislike of making you bored. Indeed, the Messenger of Allah (may Allah bless him and grant him peace) used to attend to us with admonition on certain days, fearing boredom for us.”
