Surah Al-Baqara Verse 76

وَإِذَا لَقُوا الَّذِينَ آمَنُوا قَالُوا آمَنَّا وَإِذَا خَلَا بَعْضُهُمْ إِلَىٰ بَعْضٍ قَالُوا أَتُحَدِّثُونَهُم بِمَا فَتَحَ اللَّهُ عَلَيْكُمْ لِيُحَاجُّوكُم بِهِ عِندَ رَبِّكُمْ ۚ أَفَلَا تَعْقِلُونَ

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

Translation / The Meaning
