After her death, Shah Jahan went into deep grief. He was paralysed with grief. He cried for days and weeks on end. And it is said that he was in isolation for a year mourning the death of his wife. When he appeared again, it’s said that his hair had turned white. His back was bent and his face showed his despair.
In Islamic theology, it is believed that the body of the deceased turns into soil. but the soul remains in the grave. Later, on Judgement Day, the souls will return to the Creator, when it’ll be decided if the soul would go to heaven or hell.
So the grave is known as the final resting place of a soul. Shah Jahan believed that the final resting place of Mumtaz Mahal, should be grand. Unparalleled. When he decided to build the Taj Mahal, the Chief Architect was Ustad Ahmad Lahori, was bestowed the title ‘Nadir-e-Asr’, The Wonder of the Age. The calligraphy on the white marble panels, was done by Abdul Haq Shirazi.
