فَإِنْ كَثُرَ الْقَوْلُ وَقَلَّ النَّفْعُ، فَبِمَ نَفْتَخِرُ؟
If speech multiplies while benefit is small, what is there to boast about?
First identify the conditional in, the quantitative contrast between kathura and qalla, and the interrogative form bi-mā naftakhiru. Then use the debate’s context: the speaker is challenging misplaced pride rather than requesting an itemised answer.
The final step explains the claim’s consequence: actual benefit, not the quantity of claims made in the name of knowledge, becomes the criterion. A complete solution links grammar, sense, context and effect.
