Kashf al-Ma'aanee of Ibn Jama'aah - Juzz 27

Follow @AhleDhikr Surah an-Najm 

إِنْ هِيَ إِلَّا أَسْمَاءٌ سَمَّيْتُمُوهَا أَنْتُمْ وَآبَاؤُكُمْ مَا أَنْزَلَ اللَّهُ بِهَا مِنْ سُلْطَانٍ ۚ إِنْ يَتَّبِعُونَ إِلَّا الظَّنَّ وَمَا تَهْوَى الْأَنْفُسُ ۖ وَلَقَدْ جَاءَهُمْ مِنْ رَبِّهِمُ الْهُدَىٰ

“They follow but a guess and that which they themselves desire” [53:23]

And, 

وَمَا لَهُمْ بِهِ مِنْ عِلْمٍ ۖ إِنْ يَتَّبِعُونَ إِلَّا الظَّنَّ ۖ وَإِنَّ الظَّنَّ لَا يُغْنِي مِنَ الْحَقِّ شَيْئًا 

“They follow but a guess, and verily, guess is no substitute for the truth” [53:28]

Guessing and conjecture has been mentioned twice in close succession. 

The first Aayah blames them for their false beliefs (taking idols and gods besides Allaah). Whereas the second Aayah blames them for their false practices (naming the Angels with female names). Both types of falseness (‘Aqeedah and acts of worship) have been described as “guesswork”. 

Surah ar-Rahmaan

الرَّحْمَٰنُ {1}

عَلَّمَ الْقُرْآنَ {2}

“The Most Beneficent (Allah)! Has taught (you mankind) the Qur'an (by His Mercy)” [55:1-2]

After Praising Himself and starting the Surah by the name “ar-Rahmaan”, and the Aayah that follows is shows His Favour upon us by sending us the Quraan; “Has taught (you mankind) the Qur'an”.
