The correct answer is Option (2) → Abu’l Hasan al Hujwiri

In 1039 Abu’l Hasan al Hujwiri, a native of Hujwir near Ghazni in Afghanistan, was brought across the Indus as a captive of the invading Turkish army. He settled in Lahore and wrote a book in Persian, the Kashf-ul-Mahjub (Unveiling of the Veiled), to explain the meaning of tasawwuf and the sufis who practised it. He is revered even today as Data Ganj Bakhsh, ‘the giver who bestows treasures’, and his tomb in Lahore is called Data Darbar.
