Chach Nama

The Chach Nama (Sindhi: چچ نامو‎; Urdu: چچ نامہ‎; "Story of the Chach"), also known as the Fateh nama Sindh (Sindhi: فتح نامه سنڌ‎; "Story of the conquest of Sindh"), and as Tarekh-e-Hind wa Sindh (Arabic: تاريخ الهند والسند‎‎; "History of India and Sindh"), is one of the main historical sources for the history of Sindh in the seventh to eighth centuries CE, written in Persian.

Thus it chronicls the Chacha Dynasty's period, following the demise of the Rai Dynasty and the ascent of Chach of Alor to the throne, down to the Arab conquest by Muhammad bin Qasim in early 8th century CE. The text concludes with 'an epilogue describing the tragic end of the Arab commander Muḥammad b. al-Ḳāsim and of the two daughters of Dāhir, the defeated king of Sind'.
