The Messenger of Allah ﷺ offered the morning prayer. When he finished it, he stood up and said three times: False witness has been made equivalent to attributing a partner to Allah. He then recited: "So avoid the abomination of idols and avoid speaking falsehood as people pure of faith to Allah, not associating anything with Him. (Using translation from Abū Dāʾūd 3599)
صَلَّى رَسُولُ اللهِ ﷺ صَلَاةَ الصُّبْحِ فَلَمَّا انْصَرَفَ قَامَ قَائِمًا فَقَالَ عَدَلَتْ شَهَادَةُ الزُّورِ الْإِشْرَاكَ بِاللهِ ﷻ ثُمَّ تَلَا هَذِهِ الْآيَةَ {وَاجْتَنِبُوا قَوْلَ الزُّورِ حُنَفَاءَ لِلَّهِ غَيْرَ مُشْرِكِينَ بِهِ} [الحج 31]
