Deus Persa

Nor is Allah referred to as 'Our Father, who art in heaven', because, as a truly transcendent deity, he must transcend gender as well. The God of Islam encompasses both traditionally 'male' attributes such as those of generation and domination and 'female' attributes, such as those of loving-kindness and nurturance. Allah is called 'He' only because of the nature of the Arabic language, which assigns make or female to all nouns and pronouns. Indeed, it is probably not coincidental that so much mystical poetry in Islam has been written in Persian, a language with no gender markers to convey unintended theological limitations.
