Haşr 12-13:

•  Eğer onlar yurtlarından sürülseler, (o münafıklar) onlarla birlikte çıkmazlar, onlara karşı savaş açılacak olsa, yardım etmezler, varsay ki, yardım ettiler, sonunda arkalarını dönüp kaçıp giderler, kimseden de yardım alamazlar. Onların içlerinde size karşı duydukları korku, Allah(cc)'a karşı duydukları korkudan daha baskındır. Bu onların hakikatı kavramaktan aciz bir topluluk olmalarındandır.
  (
  Onlar Allah'a  inanmadıklarından yahut  en  azından  inanç  konusunda  yarım-gönüllü  olduklarından,  bu  dünyada  karşılaşacakları maddî/somut tehlikeler onları Allah'ın nihaî yargısı  düşüncesinden  daha fazla korkutur.ESED
  
  Bu  âyetler  nifakın  bir  inanç  problemi  ol­maktan çok bir "inanç ahlâkı"  problemi  oldu­ğunu  gösterir. MI
  
  
  يَفْقَهُونَ (yafqahuna) is a verb in Arabic that means "they understand" or "they comprehend". It is derived from the root فَقَهَ (faqaha), which means "to understand" or "to comprehend".
  
  In the sentence you provided, يَفْقَهُونَ is in the third person plural form, indicating that the subject of the sentence (they) understands something. The negation of the verb with لَّا (laa) indicates that the understanding is absent, so the sentence translates to "they do not understand".
  
  Here are some other examples of how يَفْقَهُونَ can be used in different contexts:
  
  * يَفْقَهُونَ اللَّهَ (yafqahuna Allah) - They understand God.
  * يَفْقَهُونَ الْحَقَّ (yafqahuna al-haqq) - They understand the truth.
  * يَفْقَهُونَ كِتَابًا (yafqahuna kitaban) - They understand a book.
  * يَفْقَهُونَ مَعْنَاهَا (yafqahuna ma'naaha) - They understand its meaning.
  -----------
  the word "יָפִיק" (yafik) might be a better fit. It means "to be dense, dull, or stupid," and can imply a lack of comprehension or understanding.
  
  Here are a few examples of how "יָפִיק" (yafik) can be used in different contexts:
  
  * הוּא יָפִיק בְּמַתָּנָה (hu yafik b'matana) - He is dense when it comes to learning.
  * הִיא יָפִיקָה בְּכָל שָׁכֶנָה (hi yafikah b'chol shiknah) - She is stupid in every way.
  * הוּא יָפִיק לְהִבִּין אֶת הַדָּבָר (hu yafik l'hibin et hadavar) - He is unable to comprehend the matter.
  
  It's worth noting that "יָפִיק" (yafik) can be a derogatory term, so it's important to use it with care and sensitivity.
  -----------
  The example I provided earlier, "יָפִיק" (yafik), is actually a Hebrew word, not Arabic. And you are right that it comes from the same root as the Arabic word "يَفْقَهُ" (yafqah) that we discussed earlier.
  
  The Hebrew word "יָפִיק" (yafik) is derived from the same root as the Arabic word, which is فَقَهَ (faqaha), meaning "to understand" or "to comprehend." The Hebrew word "יָפִיק" (yafik) has a similar meaning to the Arabic word, and can be translated as "dense," "stupid," or "dull."
  
  It's not uncommon for words to be shared across different languages, especially when they are closely related like Arabic and Hebrew. Both languages are part of the Semitic branch of the Afro-Asiatic language family, and they share many cognates, or words that are similar in both languages due to their shared ancestry. llama2-70b
