He is remembered as a popular statesman who did not discriminate against those of other ethnicities or religions. He hired Brahmins as his ministers and generals. For example Madanna, a Telugu Brahmin from Hanamkonda, was his Chief Minister. Tana Shah gained a place in the Telugu literature due to Kancharla Gopanna, nephew of Madanna. Kancharla Gopanna is famously known as "Ramadasu". Ramadasu lived in Nelakondapalli City in Palvancha county. Tani Shah hired him as "Thesildar" (head of the revenue department) of Palvancha county. Ramadasu diverted the public funds to construct a Rama temple in Bhadrachalam and for the jewelry for the idols of Rama, Sita and Lakshmana. Tana Shah found Ramadasu guilty of misappropriation of public funds and put him in jail. Later, according to legend, Tana Sha released Ramadasu from jail because Lord Rama appeared to him in person and paid back the money. For this goodwill gesture to Ramadasu, Tana Shah gained praise of the Telugu people.
Earlier Tana Shah's father-in-law Abdulla Qutub Shah was forced by Aurangzeb to acknowledged the suzerainty of Shah Jahan. About the year 1683, Abul Hasan appears to have become irregular in payments of taxes to the Mughals.
Refusal to pay taxes and accede to Mughal supremacy lead Aurangzeb on a campaign to reassert the rule of Mughals on Golconda. He attacked Golconda. Tana Shah defended the fort for eight months, but Aurangazeb succeeded in capturing Golconda by bribery at the end in September 1687. Tana Shan was taken as a prisoner and was imprisoned in the Daulatabad fort (near Aurangabad) where he died in prison after 12 years of captivity. When the Sultan died, he was not buried alongside his ancestors and other Qutub Shahi kings but in a modest grave between Daultabad and Aurangabad.
After the fall of Golconda on September 22, 1687, it became a part of the six Mughal provinces in the Deccan. Mahabat Khan who was initially the Commander of the Qutb Shahi army and had switched loyalty to the Mughals was appointed the Governor of Golconda-which was to become Hyderabad state under the Nizams-by Aurangzeb.
