﴿ وَإِنَّ رَبَّكَ لَيَعْلَمُ مَا تُكِنُّ صُدُورُهُمْ وَمَا يُعْلِنُونَ ﴾

“But, verily, thy Sustainer knows all that their hearts conceal as well as all that they bring into the open:”

(Lo! thy Lord) O Muhammad (knoweth surely all that their bosoms hide) of hatred and enmity, (and all that they proclaim) and all that they display of disbelief, idolatry and aggression.
