The Prophet ﷺ led the dawn prayer, and when he finished, he stood up and declared, "False testimony has been equated with associating partners with Allah," repeating it three times. Then he recited this verse, "And shun false speech, being upright for Allah, not associating anything with Him" [Hajj 22:30–31].
حدثنا أبو بكر بن أبي شيبة حدثنا محمد بن عبيد حدثنا سفيان العصفري عن أبيه عن حبيب بن النعمان الأسدي
صلى النبي ﷺ الصبح فلما انصرف قام قائما فقال عدلت شهادة الزور بالإشراك بالله ثلاث مرات ثم تلا هذه الآية {واجتنبوا قول الزور حنفاء لله غير مشركين به}
[Its chain is daif] Abu Dawud narrated it in the Book of Judgments, chapter on false testimony, hadith no. 3599, from Muhammad bin Ubayd through this same route. Its defect is the unknown status of Abu Sufyan Ziyad Usfuri and his teacher Habib bin Numan, and Allah knows best their true status.
