He who visits a diviner ('Arraf) and asks him about anything, his prayers extending to forty nights will not be accepted. (Using translation from Muslim 2230)   

عَنْ بَعْضِ أَزْوَاجِ النَّبِيِّ ﷺ عَنِ النَّبِيِّ ﷺ قَالَ مَنْ أَتَى عَرَّافًا فَصَدَّقَهُ بِمَا يَقُولُ لَمْ تُقْبَلْ لَهُ صَلَاةٌ أَرْبَعِينَ يَوْمًا  

[Machine] Some of the companions of the Prophet ﷺ narrated that the Prophet ﷺ saw in a dream a man pouring water on his head while he was fasting, either due to heat or thirst.  

عَنْ بَعْضِ أَصْحَابِ النَّبِيِّ ﷺ أَنَّ النَّبِيَّ ﷺ رُئِيَ بِالْعَرْجِ وَهُوَ يَصُبُّ عَلَى رَأْسِهِ الْمَاءَ وَهُوَ صَائِمٌ مِنَ الْحَرِّ أَوِ الْعَطَشِ
