He said, the Messenger of Allah ﷺ led the dawn prayer, and when he finished he stood up and said, "False testimony has been equated with associating partners with Allah," repeating it three times. Then he recited, "So avoid the filth of idols, and avoid false speech, being upright for Allah, not associating anything with Him" [Hajj 22:30–31].
حدثني يحيى بن موسى البلخي حدثنا محمد بن عبيد حدثني سفيان يعني العصفري عن أبيه عن حبيب بن النعمان الأسدي
قال صلى رسول الله ﷺ صلاة الصبح فلما انصرف قام قائما فقال عدلت شهادة الزور بالإشراك بالله ثلاث مرار ثم قرأ {فاجتنبوا الرجس من الأوثان واجتنبوا قول الزور حنفاء لله غير مشركين به}
[Its chain is daif] Tirmidhi narrated it, in the Book of Testimonies, chapter on what has been said concerning false testimony, no. 2300, and Ibn Majah, no. 2372, from the hadith of Muhammad bin Ubayd, by this chain. Habib bin Numan is of unknown status, no one but Ibn Hibban rated him reliable, and the narrator from him is not known who he is. The hadith has a daif corroborating narration in Tirmidhi.
