Sahih Bukhari 6301

حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ ، حَدَّثَنَا اللَّيْثُ ، عَنْ عُقَيْلٍ ، عَنِ ابْنِ شِهَابٍ ، قَالَ : أَخْبَرَنِي حُمَيْدُ بْنُ عَبْدِ الرَّحْمَنِ ، أَنَّ أَبَا هُرَيْرَةَ ، قَالَ : قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : مَنْ حَلَفَ مِنْكُمْ ، فَقَالَ فِي حَلِفِهِ : بِاللَّاتِ وَالْعُزَّى ، فَلْيَقُلْ : لَا إِلَهَ إِلَّا اللَّهُ ، وَمَنْ قَالَ لِصَاحِبِهِ : تَعَالَ أُقَامِرْكَ ، فَلْيَتَصَدَّقْ .

Narrated Abu Huraira: Allah's Apostle said, Whoever among you takes an oath wherein he says, 'By Al-Lat and Al-`Uzza,' names of two Idols worshipped by the Pagans, he should say, 'None has the right to be worshipped but Allah; And whoever says to his friend, 'Come, let me gamble with you ! He should give something in charity. (See Hadith No. 645)
