Oaths and Vows
Section 1
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 (ﷺ) 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.)
