Mishkat al-Masabih 15 Oaths and Vows كتاب الإيمان والنذور 4

وَعَنْ أَبِي هُرَيْرَةَ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: ” مَنْ حَلَفَ فَقَالَ فِي حَلِفِهِ: بِاللَّاتِ وَالْعُزَّى فَلْيَقُلْ: لَا إِلَهَ إِلَّا اللَّهُ. وَمَنْ قَالَ لِصَاحِبِهِ: تَعَالَ أقامرك فليتصدق ”

Abu Huraira reported the Prophet as saying that if anyone swears an oath in the course of which he says, “By al-Lat and al-‘Uzza”, he should say, “There is no god but God”; and that if anyone says to his friend, “Come and let me play for money with you”, he should pay sadaqa . (Bukhari and Muslim.)
