Why Does say "WE" and "HE"
The term "We" in the Quran is the royal "We" - as an example when the
king says, "We decree the following declaration, etc." or, "We are not
amused." It does not indicate plural; rather it displays the highest
position in the language. English, Persian, Hebrew, Arabic and many
languages provide for the usage of "We" for the royal figure. It is
helpful to note the same dignity is given to the person being spoken to in
English. We say to someone, "You ARE my friend." Yet the person is only
one person standing there. Why did we say "ARE" instead of "IS"? The noun
"you" is singular and should therefore be associated with a singular verb
for the state of being, yet we say, "are." The same is true for the
speaker when referring to himself or herself. We say, "I am" and this is
also in the royal plural, instead of saying, "I is."
When Allah uses the term "HE" in Quran it is similar to the above answer.
The word "He" is used when referring to Allah out of respect, dignity and
high status. It would be totally inappropriate to use the word "it" and
would not convey the proper understanding of Allah being who Allah is;
Alive, Compassionate, Forgiving, Patient, Loving, etc. It is not correct
to associate the word "He" with gender, as this would be comparing Allah
to the creation, something totally against the teaching of Quran.
Furthermore, some are of the view that masculinity represent majesty and
feminity denotes meekness and softness. And as the primary relation of man
with Allah is that humble servant to His lord so the masculine pronoun
suits more the divine majesty.
The notion that husband is "majaazi khuda" cannot be traced within the
teachings of Islam. Therefore, it's baseless. However the tradition
regarding the sajdah could be traced easily in our books of Hadith.
Likewise there are traditions that curse men who do not respect their
wives. All these traditions and the likes are only indicating to the
importance of mutual respect within marriage.
The distribution of two sajdahs between God and husband has no truth
behind it. It's baseless and cannot be traced within our teachings.
