From Indian Kanoon:
“ It is reported that it was at the Taj Mahal Hotel ballroom that, on February 20, 1918, at her eighteenth birthday party, Ruttie had accepted Mr Jinnah’s hand in marriage while the band was playing the Chopin tune, So Deep is the Night. It is also reported that both Mr. Jinnah, the creator of Pakistan, and Mrs. Sarojini Naidu, the President of the Indian National Congress, often held court at Taj Mahal Hotel.
Mr. Jinnah also had an intimate connection with Mazgaon, where the bomb planted by two terrorists in a taxi exploded, killing three (3) and wounding nineteen (19) people. It is reported that Mr. Jinnah devoted Thursday afternoons to visiting the grave of his wife Ruttie at the Khoja Shiite Isna’ashri Cemetry, situated at Mazgaon, Mumbai.
One wonders what Quaid-e-Azam would have thought of the terrorist attack on his favourite city in the subcontinent and especially on Taj Mahal Hotel, with which he had a personal relationship of a very intimate kind.”
