Whoever swears by Al-Lāt and Al-‘Uzza should say: 'there is no god but Allah'. Whoever says to his companion 'Come and gamble with me’ should give charity. [Muslim]
«من حَلَفَ فقال في حَلِفِهِ: بِاللاَّتِ وَالْعُزَّى، فليقل: لا إله إلا الله، ومن قال لصاحبه: تعال أُقَامِرْكَ فَلْيَتَصَدَّقْ». (مسلم)
