The word(s) "assault" appears 2 time(s) in 2 verse(s) in Quran in Mohsin Khan translation.

(1) Two men of those who feared (Allah and) on whom Allah had bestowed His Grace (they were يوشع وكالب Yusha' and Kalab) said: "assault them through the gate; for when you are in, victory will be yours; and put your trust in Allah if you are believers indeed."

(2) "And befool them gradually those whom you can among them with your voice (i.e. songs, music, and any other call for Allah's disobedience), make assaults on them with your cavalry and your infantry, share with them wealth and children (by tempting them to earn money by illegal ways - usury, or by committing illegal sexual intercourse), and make promises to them." But Satan promises them nothing but deceit.
