Bangladesh is a new country, it was part of India, It become east Pakistan and then they fought with the Pakistanis with the help of India to become an independent state in 1971. There was no Bangladesh before that. You also have to remember the mass migration of Hindus and Muslims to new countries after they were made.

Yes, according to that logic - which is correct, before the beginning there was Allah, there was nothing before him and nothing with Him,
fast forward,
the whole sky and worlds were gas, then liquid out of which appeared solid, out of which appeared species, and when adam matured, the guidance of Allah began to come down to assist in the navigation, operation and interaction, then there appeared tribes, and every time they forsook the guidance of Allah and good use of intellect and reason, they corrupted and messed up and became enemies, then Allah sent Noah, and then He sifted them and left the sane ones, then they slowly forsook the guidance of Allah and became ignorant and messed up again, then Allah sent Abraham pbuh, and so on.....
Innit?
Fast forward, then it is recorded that in the east there was al hind, then the Muslims came to the north, and shah jalal al yemeni saw a dream where he called a spade a spade, and he asked his uncle, who gave him a handful of soil and told him to settle and propagate Islam in the region where the soil matched, so he set off eastwards, and when he reached al hind, the complaint of burhanuddin arrived from northern bengal, and he set off in the name of Allah, he came he saw, and he conquered with the word of God, and settled, then the east india trading company came, and the mughal emperor wanted luxurious and rare gifts for his palace in exchange for allowing them to trade,

....For confirmation of our love and friendship, I desire your Majesty to command your merchants to bring in their ships of all sorts of rarities and rich goods fit for my palace; and that you be pleased to send me your royal letters by every opportunity, that I may rejoice in your health and prosperous affairs; that our friendship may be interchanged and eternal"
—Nuruddin Salim Jahangir,*Letter to James I.
In 1634,
the Mughal emperor extended his hospitality to the English traders to the region of*Bengal, and in 1717 completely waived customs duties for the trade.*
William Hedges*was sent
in 1682
to*Shaista Khan, the*Mughal*governor of Bengal in order to obtain a*firman, an imperial directive that would grant England regular trading privileges throughout the Mughal Empire.
However, the company's governor in London, Sir*Josiah Child, interfered with Hedges's mission, causing Mughal Emperor*Aurangzeb*to break off the negotiations.
In 1689
a Mughal fleet commanded by*Sidi Yaqub*attacked Bombay. After a year of resistance the EIC surrendered in 1690, and the company sent envoys to Aurangzeb's camp to plead for a pardon.
The company's envoys had to prostrate themselves before the emperor, pay a large indemnity, and promise better behaviour in the future.
The emperor withdrew his troops and the company subsequently reestablished itself in Bombay and set up a new base in*Calcutta.
In September 1695,
Captain*Henry Every, an English pirate on board the*Fancy, reached the Straits of*Bab-el-Mandeb, where he teamed up with five other pirate captains to make an attack on the Indian fleet making the annual voyage to*Mocha.
The*Mughal*convoy included the treasure-laden*Ganj-i-Sawai, reported to be the greatest in the Mughal fleet and the largest ship operational in the*Indian Ocean, and its escort, the*Fateh Muhammed. They were spotted passing the straits en route to*Surat. The pirates gave chase and caught up with the*Fateh Muhammed*some days later, and meeting little resistance, took some £50,000 to £60,000 worth of treasure.

Every continued in pursuit and managed to overhaul the*Ganj-i-Sawai, who put up a fearsome fight but it too was eventually taken.
The ship carried enormous wealth and, according to contemporary East India Company sources, was carrying a relative of the Grand Mughal, though there is no evidence to suggest that it was his daughter and her retinue.
The loot from the*Ganj-i-Sawai*totalled between £325,000 and £600,000, including 500,000 gold and silver pieces,
and has become known as the richest ship ever taken by pirates.
The plunder of*Aurangzeb's treasure ship had serious consequences for the English East India Company.
The furious Mughal Emperor Aurangzeb ordered*Sidi Yaqub*and*Nawab Daud Khan*to attack and close four of the company's factories in India and imprison their officers, who were almost lynched by a mob of angry*Mughals, blaming them for their countryman's depredations, and threatened to put an end to all English trading in India.
To appease Emperor Aurangzeb and particularly his*Grand Vizier*Asad Khan, Parliament exempted Every from all of the Acts of Grace (pardons) and amnesties it would subsequently issue to other pirates.
By 1803 the lands and people he oversaw were occupied by the EIC opium smugglers.
they formed a mercenary army, and in two hundred years removed him, then the riots began, then the british monarchy took over, then the templar remnants who had formed into the society of masons, which the east india company introduced to influential businessmen and sleazy intellectuals in india also decided the time had come for world government, so they partitioned al hind, and sylhet almost went to assam, but the sylhetis went beserk, then there was a referendum, and the sylhetis chose the islamic republic which was on the bengal front, which was not an islamic state, so the Muslim intellectuals like abul ala maududi who understood islam fumed, and then it was made a nationalist state anyways, and then the UN was made by rockefellers, then the partition of al Quds which the british masons had named renamed palestine, which reminded those who knew scripture of the ancient pagan philistines, and then there was meetings, and the un was meant to end all wars, but the us used it as a babbling stage. So the Muslims realised they need the guidance of Allah and khilafah.
And now Allah is about to give a take it or leave it offer on the guidance, judge, then close the book.
