أَبُو بَكْرِ بْنُ بَشِيرٍ، عَنْ وَاثِلَةَ

[Machine] I heard the Messenger of Allah ﷺ saying, "Whoever goes to a fortune-teller and asks him about something that was concealed from him, his prayers will not be accepted for forty nights. And if he believes in what the fortune-teller says, then he has disbelieved."  

الطبراني:١٨٤٦٣ – حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ الْعَزِيزِ ثنا سُلَيْمَانُ بْنُ أَحْمَدَ الْوَاسِطِيُّ ثنا يَحْيَى بْنُ الْحَجَّاجِ ثنا عِيسَى بْنُ سِنَانٍ عَنْ أَبِي بَكْرِ بْنِ بَشِيرٍ قَالَ سَمِعْتُ وَاثِلَةَ بْنَ الْأَسْقَعِ يَقُولُ

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «مَنْ أَتَى كَاهِنًا فَسَأَلَهُ عَنْ شَيْءٍ حُجِبَتْ عَنْهُ التَّوْبَةُ أَرْبَعِينَ لَيْلَةً فَإِنْ صَدَّقَهُ بِمَا قَالَ كَفَرَ»
