An-Nur - 24:12

لَوْلَا إِذْ سَمِعْتُمُوهُ ظَنَّ الْمُؤْمِنُونَ وَالْمُؤْمِنَاتُ بِأَنفُسِهِمْ خَيْرًا وَقَالُوا هَذَا إِفْكٌ مُّبِينٌ
[24:12]
Why did not the believing men and the believing women, when you heard it, think well of their own people, and say: This is an evident falsehood?
Why did not the believers - men and women - when ye heard of the affair,- put the best construction on it in their own minds and say, "This (charge) is an obvious lie"?
Why did not the believers, men and women, when ye heard it, think good of their own own folk, and say: It is a manifest untruth?
