Musannaf Ibn Abi Shaybah

Hazrat Salih al-Qadadi narrates that my family sent me to Hazrat Sa'id bin Jubayr with a gift. I reached his door while he was performing ablution. I said: "May I come in?" He remained silent three times. He said: "Say: As-salamu 'alaykum." The narrator says, then I entered, and he said: "I did not see you following the way of the Sunnah, so I have taught you the Sunnah."
