Al-Ahzaab • EN-AL-JALALAYN
﴿ إِن تُبْدُوا۟ شَيْـًٔا أَوْ تُخْفُوهُ فَإِنَّ ٱللَّهَ كَانَ بِكُلِّ شَىْءٍ عَلِيمًۭا ﴾
“Whether you do anything openly or in secret, [remember that,] verily, God has full knowledge of everything.”
Whether you disclose anything or keep it hidden regarding marrying them after him truly God has knowledge of all things and will requite you for it.
