Musannaf Ibn Abi Shaybah 7091 — Qunut before or after bowing

Sayyiduna Abdullah (bin Mas'ud) (may Allah be pleased with him) said that the Prophet (peace and blessings be upon him) used to recite the qunut supplication in witr before the bowing (ruku'). Abdullah said: I sent my mother, Umm Abd (may Allah be pleased with her), and she spent the night with the wives of the Prophet (peace and blessings be upon him); then she told me that he (peace and blessings be upon him) recited the qunut supplication in witr before the bowing (ruku').
