I think land of Pakistan & Kashmir is properly Al-Hind. And these lands are overwhelmingly Muslim lands.
Hindustan do have Stamb and the reason were Non - Hindu Tribes Kingships mainly Tunani & Moo Gools !!!
However, I think that the easterly lands of Bharat (which means "Spices" in Arabic language) is not Al-Hind.
In India, Research is being on Harut Wa Marut !!!
Harata name is linked with Ishtun ( Angels ) ; Ishtun in Arabic Language & Ishwara in Sanskrit Language are the same Link !!!
If we study the Hadith which were revealed in Arabic language, then we should attribute Arab geographical terms, instead of British terms which contrastively called the Entire Subcontinent as "India".
Origin of Compass has nothing to do with Anglo Saxons !!!
The reason , Indian themselves use to term Sub Continent because of the Territory of the Hindu Rashtra is Occupied !!! Inshallah Soon We Hindustanis will use the term Whole Continent !!!
The British were confused by the word "Derya" (which means both Ocean and River in Persian/Ordu language)... There is Derya-i-Hind (Hind River located in Pakistan) and Derya-i-Hind (Hind Ocean between Karachi & Sri-Lanka)...
Darya e Aum & Darya e Hindu are there in Islamic Republic of Afghanistan !!!
Already Darya e Hindu is termed as River Indus !!!
Understand the importance of Khorasan !!! You are not a Statesman nor the Blessed one !!! Allah Rabbul Alameen ka Waada Saacha Hai !!!
However due to massive conquest by the English, the word Hind became applied to the latter, the land from of the Kutch (East of Karachi) all the way along the coast of Bharat to Sri Lanka & likewise on the Easterly coast of Bharat as all these lands were now controlled by the English..
In Keep the Sovereignty of United States of America from the European Colonizers; Arabs & Hindus spread English Language , Arabs and Hindus are the Largest Speakers of English Language !!!
However, what is a true bummer is that the Bharti major religion of Dharma is unfortunately called Hinduism in English, rooting from Hind, which makes this word forever stolen by them.
Dhara e Bhagwan Shree Ram is Arya Dharma !!!
It is now very hard to associate Islamic South Asians with Hind. It is very hard for the Bharti to digest that Hind is Islamic. And by stealing this word of Hind, it keeps alive their Dharma false association with Hind when they are Bharti (Spiced) which is distinct identity.
Believers do belief in the Existence of Celestial Beings !!! Believers don't worship Angels !!!
Adom Alai Salaam & Hinda Alai Salaam came from Heavens to BhoomiMandal / Earth !!! Now think Why Ins is the Best Creation of Allah Rabbul Alameen ??? Koun Kiske Humsar Hai ???
