Riyad as-Salihin, Book 18, Hadith 1807 (In-Book) ⓘ

Abu Hurairah (May Allah be pleased with him) said: The Prophet said, "He who takes an oath and involuntarily says: 'By Al-Lat and Al-'Uzza' should at once affirm: 'La ilaha illallah (there is no true god except Allah)', and he who says to his companion: 'Come let's gamble' should make expiation by giving something in charity."[Al-Bukhari and Muslim].

وعن أبي هريرة رضي الله عنه عن النبي صلى الله عليه وسلم قال‏:‏ “من حلف فقال في حلفه‏:‏ باللات والعزى، فليقل‏:‏ لا إله إلا الله، ومن قال لصاحبه‏:‏ تعالى أقامرك فليتصدق‏"‏ ‏(‏‏(‏متفق عليه‏)‏‏)‏‏.‏
