The Ramayan by Valmiki

To Indrajit the bold and brave The giant king his mandate gave: "O trained in warlike science, best In arms of all our mightiest, Whose valour in the conflict shown To Asurs and to Gods is known, The Kinkars whom I sent are slain, And Jambumali and his train; The lords who led our giant bands Have fallen by the monkey's hands; With shattered cars the ground is spread, And Aksha lies amid the dead. Thou art my best and bravest: go, Unmatched in power, and slay the foe." He heard the hest: he bent his head; Athirst for battle forth he sped. Four tigers fierce, of tawny hue, With fearful teeth, his chariot drew.

Hanuman heard his strong bow clang, And swiftly from the earth he sprang, While weak and ineffective fell The archer's shafts though pointed well. The Rakshas saw that naught might kill The wondrous foe who mocked his skill, And launched a magic shaft to throw A binding spell about his foe. Forth flew the shaft: the mystic charm Stayed his swift feet and numbed his arm, Through all his frame he felt the spell, And motionless to earth he fell. Nor would the reverent Vanar loose The bonds that bound him as a noose. He knew that Brahma's self had charmed The weapon that his might disarmed.
