Ayesha reported,

Abu Bakr had a servant who used to bring him a share of his earnings, and Abu Bakr would eat from it. One day the servant brought something, and Abu Bakr ate from it.The servant asked him, "Do you know what this is?"Abu Bakr replied, "What is it?"The servant said, "I had practiced fortune-telling for someone during the days of ignorance, though I had no real skill in it and merely deceived him. He met me later and gave me this in payment for what I had done, and this is what you have just eaten from."Abu Bakr then put his hand into his mouth and vomited up everything in his stomach.

عن عائشة رضي الله عنها قالت

كان لأبي بكر غلام يخرج له الخراج وكان أبو بكر يأكل من خراجه فجاء يوما بشيء فأكل منه أبو بكر فقال له الغلام أتدري ما هذا فقال أبو بكر وما هو قال كنت تكهنت لإنسان في الجاهلية وما أحسن الكهانة إلا أني خدعته فلقيني فأعطاني بذلك فهذا الذي أكلت منه فأدخل أبو بكر يده فقاء كل شيء في بطنه
