«وَأَجْلِبْ عَلَيْهِمْ بِخَيْلِكَ وَرَجِلِكَ»
“And rally against them your cavalry and your infantry.” (al-Isrāʾ 17:64, excerpt)
The expression summons the scene of an advancing army, with mounted troops and foot soldiers. In the surrounding speech addressed to Satan, the image conveys the reach, variety and urgency of forces used for misguidance.
The pairing of cavalry and infantry broadens the imagined assault. Its interpretive value lies in making the moral contest vivid. Reading the metaphorical force does not demand the claim that each individual must literally see military formations in the situation described.
