We did test those who have gone before them. Allah has to see    (for the purpose of reward and punishment) who are the truthful    and who are the liars.
   - Muhammad Farooq-i-Azam Malik
   We certainly tested those before them. And 'in this way' Allah will clearly distinguish between those who are truthful and those who are liars.
   - Mustafa Khattab
     
Lo! We tested those who were before you. Thus Allah knoweth those    who are sincere, and knoweth those who feign.
   - Marmaduke Pickthall
   We did test those before them and Allah will certainly know those    who are true from those who are false. 3424
