It is narrated from Hazrat Khuraim (may Allah be pleased with him) that once the Holy Prophet (peace and blessings be upon him) offered the Fajr prayer. When he finished the prayer, he stood at his place and said: False testimony has been equated with shirk (associating partners with Allah). Then the Holy Prophet (peace and blessings be upon him) recited this verse: "Avoid false speech, devote yourselves exclusively to Allah, and do not associate anyone with Him."
