عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ((مَا اقْتَبَسَ رَجُلٌ عِلْمًا مِنَ النُّجُومِ إِلَّا اقْتَبَسَ شُعْبَةً مِنَ السِّحْرِ مَا زَادَ زَادَ)).
It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: Whoever learns astrology has learned a branch of magic; the more he increases in learning astrology, the more he increases in learning magic.
