Musannaf Ibn Abi Shayba 33:627

Hafs narrated to us, from Ash'ath, from Ibn Sirin, from al-Rabi' ibn Khuthaym, who said: Lessen your speech, except for nine things: glorifying Allah (tasbih), declaring the oneness of Allah (tahlil), magnifying Allah (takbir), praising Allah (tahmid), asking for good, seeking refuge from evil, enjoining good, forbidding evil, and reciting the Quran.
