Commentary
Described in the previous verses were the hypocrites of Madinah. The present verses mention hypocrites who lived on the desert around the outskirts of Madinah.
The word اَلاَعرَاب (al-a` rab) is not a plural form of اَلعَرَب (al-'arab). It is اِسم جمع (ism al jam`: collective noun) and is used for the Bedouins of the desert. In its singular form, it becomes اَلاَعرَابی (al-a` rabiyy) - similar to (al-ansariyy), the singular form of اَلاَنصَار (al-ansar).
According to their condition described in Verse At-Tawbah 9:97 ⧉ , they outdid city dwellers in disbelief and hypocrisy. The reason given is that these people generally remained ignorant and hard-hearted as they lived far away from knowledge and the knowledgeable. Then the text says: ` the Bedouins are more likely to be ignorant of the limits of what Allah has sent down.' It means that the very surroundings in which they live are such as would keep them in the dark about the limits set by Allah through the revelation - because the Qur'an does not come before them, nor do they have access to its meanings, explanations and injunctions.
