76 Wa izaa laqul lazeena

وَاِذَا لَقُوا الَّذِيْنَ اٰمَنُوْا قَالُوْٓا اٰمَنَّا ښ وَاِذَا خَلَا بَعْضُھُمْ اِلٰى بَعْضٍ قَالُوْٓا اَتُحَدِّثُوْنَھُمْ بِمَا فَتَحَ اللّٰهُ عَلَيْكُمْ لِيُحَاۗجُّوْكُمْ بِهٖ عِنْدَ رَبِّكُمْ ۭ اَفَلَاتَعْقِلُوْنَ 
وَإِذَا : And when  

  لَقُوا۟ : they meet  
  ٱلَّذِينَ : those who  
  ءَامَنُوا۟ : believed,  
  قَالُوٓا۟ : they say,  
  ءَامَنَّا : "We have believed."  
  وَإِذَا : And when  
  خَلَا : meet in private  
  بَعْضُهُمْ : some of them  
  إِلَىٰ : with  
  بَعْضٍ : some (others),  
  قَالُوٓا۟ : they say,  
  أَتُحَدِّثُونَهُم : "Do you tell them  
  بِمَا : what  
  فَتَحَ : has  
  ٱللَّهُ : Allah  
  عَلَيْكُمْ : to you  
  لِيُحَآجُّوكُم : so that they argue with you  
  بِهِۦ : therewith  
  عِندَ : before  
  رَبِّكُمْۚ : your Lord?  
  أَفَلَا : Then do (you) not  
  تَعْقِلُونَ : understand?" 
Wa izaa laqul lazeena aamanoo qaalooo aamannaa wa izaakhalaa ba'duhum ilaa ba'din qaalooo atuhaddisoonahum bimaa fatahal laahu 'alaikum liyuhaajjookum bihee 'inda rabbikum; afalaa ta'qiloon

And when they meet those who believe, they say, "We have believed"; but when they are alone with one another, they say, "Do you talk to them about what Allah has revealed to you so they can argue with you about it before your Lord?" Then will you not reason?
