Musannaf Ibn Abi Shaybah

Hasan narrates that a man sought permission (to enter) from Hazrat Jabir bin Abdullah (may Allah be pleased with him). So he recited tasbih. The man came inside and sat down until he (Jabir) finished the prayer. And (Imam) Abu Hanifa's opinion is mentioned that: he used to say, the one praying should not do so. And he considered it disliked.
