One should not swear by Al-Lat and Al-‘Uzza or by any false deities

Narrated Abu Huraira:

The Prophet ﷺ said, "Whoever swears saying in his oath. 'By Al-Lat and Al'Uzza,' should say, 'None has the right to be worshipped but Allah;
and whoever says to his friend, 'Come, let me gamble with you,' should give something in charity."

حَدَّثَنِي عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، حَدَّثَنَا هِشَامُ بْنُ يُوسُفَ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ حُمَيْدِ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ عَنِ النَّبِيِّ ﷺ قَالَ " مَنْ حَلَفَ فَقَالَ فِي حَلِفِهِ بِاللاَّتِ وَالْعُزَّى. فَلْيَقُلْ لاَ إِلَهَ إِلاَّ اللَّهُ. وَمَنْ قَالَ لِصَاحِبِهِ تَعَالَ أُقَامِرْكَ. فَلْيَتَصَدَّقْ ".
