Muhammad Abdul-Hayy Siddiqui (Urdu/Arabic: ????? ??????? ?????), writing under the pen-name Bekhud Badayuni (Urdu/Persian: ????? ???????), was one of the leading Urdu poets of the late nineteenth and early twentieth centuries.
It is customary for Urdu poets to assume a pen-name (takhallus) that can be employed as a pun in the final couplet of every ghazal, often combined with a second name that denotes the poet's place of origin.
In this case, "Bekhud", the pen-name means beside oneself (with joy or grief), out of one's mind; in ecstasy, transported, enraptured, intoxicated; senseless, delirious, commonly used in the context of spiritual ecstasy, and is paired with "Badayuni", which indicates ties to the city of Badayun.
