Musannaf Ibn Abi Shaybah 27499 — A man who asks permission without

Salih al-Qaddadi said: My family sent me to Sa'id bin Jubayr with a gift. I reached his door while he was performing ablution. I said: "May I enter?" He remained silent three times. Then he said: "Say: As-salamu alaykum (Peace be upon you)." The narrator said: Then I entered, and he said: "I did not see you following the way of the Sunnah, so I taught you the Sunnah."
