The original gateway of Saifabad is an impressive structure, built in the prevalent style of the gateways of the Mughal caravanserais of the region as may be seen in the Sarai at Rajpura, 20 km north of Bahadurgarh. The soaring facade of the gateway, with an octagonal tower crowned with a kiosk appended to its each corner, presents an impressive view. At the top of the facade appears a Persian inscription of four lines, said to have been composed by Nasir 'Ali Sirhindi, written in elegant nastaliq characters. Translated into English, this inscription reads:
God desired that (His) creatures derive benefit (and)
Its dwellers be ever happy-at-heart,
(Therefore) in the reign of emperor (of the world) Alamgir
Saif Khan populated (or founded) Saifabad.

The last line of the inscription is a chronogram which, according to the abjad calculation, comes to the date 1067 hijri. The year began on October 10, 1656, and ended on September 28, 1657. Although the inscription gives the name of Aurangzeb, Shah Jahan was the reigning emperor at that time. The coronation of Aurangzeb took place on July 21, 1658. Not only this, but just three months before the coronation, Saif Khan along with Raja Jaswant Singh was fighting against Aurangzeb. But after the defeat of the royal army, Saif Khan switched his loyalty to Aurangzeb. It appears that although Saif Khan founded the village duringthe reign of Shah Jahan, he put the inscription on the structure after Aurangzeb had ascended the throne. And it was, most probably, keeping in view the exigency of the political situation at that time that Aurangzeb allowed Saif Khan to name the village after himself. Otherwise, the Mughal nobles were not always allowed to do so.
