(52) Chapter. Every Lahw (amusement, idle talk, etc.) or deed that diverts one from fulfilling one’s obedience (duties) towards Allah, is Batil [falsehood (disbelief, etc.)].

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)
