Riyad as-Salihin 1807
Abu Hurairah (May Allah be pleased with him) said:
The Prophet (ﷺ) 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)‏‏)‏‏.‏
