Verily, Allah knows those who believe, and verily, He knows the hypocrites (i.e. Allah will test the people with good and hard days to discriminate the good from the wicked (although Allah knows all that before putting them to test))
Surely Allah knows those who believe, and those who are hypocrites (the two-faced who use their intellect in favor of their vested interests rather than for the sake of the Truth).
Sayyed Abbas Sadr-Ameli
And certainly Allah knows those who believe, and certainly He knows the hypocrites
Al-muntakhab fi tafsir al-Qur'an al-Karim
And Allah does indeed know those who acknowledge His divine nature and His Omnipotence and Authority and conformed their will to His will and also He knows the hypocrites who falsely profess to be religiously inclined
