عہد وسطی میں دہلی شہر اوراق مصور سے کم نہ تھا۔ یہ شہر عالم میں شہر انتخاب ہوا کرتا تھا اور اس کی چہل پہل اور دھوم دھام سارے عالم میں دھوم مچاتی تھی مگر دہلی پر یکایک نظر بد لگی اور دیکھتے ہی دیکھتے یہ شہر ایک ویران جگہ لگنے لگا اور اس کی رونقیں اجڑ گئیں۔ محفلیں اٹھ گئیں اور یہاں کے چائے خانے ویران ہو گئے اور محلوں میں سناٹا چھا گیا۔ اس کتاب میں عہد وسطی کی چمچماتی دلی کے گلی کوچے، یہاں کے باشندے، بازار، محلات کی رونق اور بادشاہوں کی مجلسیں اور شعرا و ادبا کی مجالس کا ذکر ہے جس سے دہلی کی خوشحالی اور اس کی چہل پہل کا ذکر کیا گیا ہے۔ خیال رہے کہ یہ ایک سالانہ نظام اردو خطبہ ہے جو پروفیسر خلیق احمد نظامی نے اس موضوع پر دیا تھا۔ دہلی یونیورسٹی میں سالانہ نظام اردو خطبات کا ایک طویل اور روشن سلسلہ ہے جو مختلف موضوعات پر دیا جاتا رہا ہے۔

Khaliq Ahmad Nizami (born 1925), an Indian historian, religious scholar, and diplomat, was best known for his work on the history of medieval India and in particular for his studies of the Muslim community of that time.

Khaliq Ahmad Nizami was born in the town of Amroha in the United Provinces of British India on December 5, 1925. He was the son of Aziz Ahmad and Sayyidah Nizami. Khaliq Ahmad received his education in India, and though he travelled extensively and gained much recognition abroad, he also largely pursued his academic career in his native country. He attended the University of Agra, where he completed the M.A. in history in 1945. In the following year he was awarded the LL.B. degree by the same institution. Married to Raziyah Nizami, the couple had five children.

In 1947 Nizami joined the staff of the Aligarh Muslim University in Aligarh, India, in the Department of History. The Aligarh Muslim University was the premier institution of higher education for Muslims in India in both pre-partition and post-partition days. In the period between 1937 and 1947 it was the foremost center of the Muslim political agitation that eventually led to the partition of India and the creation of Pakistan. Nizami was among those Muslim intellectuals who opted for Indian nationalism and the cause of the Indian National Congress. In consequence, he remained in India with his family when the country was divided in 1947.

Nizami's rise in position at Aligarh was both steady and swift. In 1953 he became reader in history, and in 1963 he was promoted to the rank of professor. The latter appointment was accompanied by his being made head of the university's Centre of Advanced Study in History, which has numbered many of the best and most famous twentieth-century historians of India among its personnel. In 1968 he gained the respected title of senior professor of the university. He also played an important part in the administration of the Aligarh Muslim University. He acted as pro-vice-chancellor in 1972-1973 and in 1974 became vice-chancellor, the highest executive officer of the institution. In 1978 he was made the Indian ambassador to Syria, but at the same time between 1978 and 1980 he served as dean of the social sciences at the university. In 1980 he became head of the Department of History at Aligarh.
