Sahih Bukhari · Hadith 4789

حدثني إبراهيم بن الحارث، حدثنا يحيى بن أبي بكير، حدثنا إسرائيل، عن أبي حصين، عن سعيد بن جبير، عن ابن عباس رضى الله عنهما قال ‏{‏ومن الناس من يعبد الله على حرف‏}‏ قال كان الرجل يقدم المدينة، فإن ولدت امرأته غلاما، ونتجت خيله قال هذا دين صالح‏.‏ وإن لم تلد امرأته ولم تنتج خيله قال هذا دين سوء‏.‏

Narrated Ibn `Abbas: Regarding the Verse: "And among men is he who worships Allah's as it were on the very edge." (22.11). A man used to come to Medina as if his wife brought a son and his mares produces offspring. He would say, "This religion (Islam) is good," but if his wife did not give birth to a child and his mares produced no offspring, he would say, "This religion is bad."
