وَعَنِ ابْنِ عَبَّاسٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنِ اقْتَبَسَ بَابًا مِنْ عِلْمِ النُّجُومِ لِغَيْرِ مَا ذَكَرَ اللَّهُ فَقَدِ اقْتَبَسَ شُعْبَةً مِنَ السِّحْرِ الْمُنَجِّمُ كَاهِنٌ والكاهنُ ساحرٌ والساحرُ كافرٌ» . رَوَاهُ رزين

Ibn ‘Abbas reported God’s messenger as saying: “If anyone acquires a section of the science of the stars for a purpose other than what God has mentioned he has acquired a branch of magic. The astrologer is a kahin , the kahin is a magician, and the magician is an infidel.” Razin transmitted it.
