Can you please explain what is meant by "females are deficiently intelligent in comparison to males".

Answer

The difficulty you have in understanding 'deficiently intelligent' in regard to women is on account of your natural attribute of Nuqs fil Aql (intellectual deficiency).

Firstly do understand that it was Rasulullah (sallallahu alayhi wasallam) who had informed that females are naaqisaatul aql (deficient in intelligence). These are the words of the Nabi (sallallahu alayhi wasallam) whom you and we believe to be the Final Rasool of Allah Ta'ala. He had further explained that females are also deficient in Deen.

When the ladies asked Rasulullah (sallallahu alayhi wasallam) to explain their deficiencies, he responded:

(1) The testimony of two women equating to the testimony of one male indicates the deficiency of their intelligence. This is substantiated by the Qur'aanic Aayat in Surah Baqarah, Aayat 282.

(2) Their inability to perform Salaat (and fast) for a number of days each month on account of haidh (menses) demonstrates their Deeni deficiency.

The Sahaabiyyah ladies understood and accepted the truth and veracity of these statements of Rasulullah (sallallahu alayhi wasallam). They entertained no doubts in this regard. Nabi (sallallahu alayhi wasallam) did not elaborate further. It is therefore superfluous for us to attempt a further elucidation, for it will merely be our opinion. There are innumerable issues of the Deen which we do not understand, but in which we believe. We do not interpret the Qur'aan and Hadith. We merely narrate the commands of Islam.
