Messenger of Allah ﷺ said, "Whomever takes an oath in which he mentions Lat and ʿUzza (forgetfully), should say: None has the right to be worshipped but Allah, and whoever says to his companion. 'Come along, let us gamble' must give alms (as an expiation).  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ حَلَفَ فَقَالَ فِي حَلِفِهِ وَاللاَّتِ وَالْعُزَّى فَلْيَقُلْ لاَ إِلَهَ إِلاَّ اللَّهُ وَمَنْ قَالَ لِصَاحِبِهِ تَعَالَ أُقَامِرْكَ فَلْيَتَصَدَّقْ
