(9) O you who have believed, remember the favor of Allah upon you when armies came to [attack] you and We sent upon them a wind and armies [of angels] you did not see. And ever is Allah, of what you do, Seeing. (10) [Remember] when they came at you from above you and from below you, and when eyes shifted [in fear], and hearts reached the throats and you assumed about Allah [various] assumptions. (11) There the believers were tested and shaken with a severe shaking.
