سنن ابن ماجه

It was narrated that Khuraim bin Fatik Al-Asadi said that : the Prophet(ﷺ) prayed the Morning prayer, and when he had finished, he stood up and said: “Bearing false witness is equivalent to associating others with Allah,” three times. Then he recited this Verse: “And shun lying speech (false statements), Hunafa' Lillah (i.e., worshiping none but Allah), not associating partners (in worship) to Him.”
