Surah An-Nur — Ayah 16 (24:16)
وَلَوۡلَآ إِذۡ سَمِعۡتُمُوهُ قُلۡتُم مَّا يَكُونُ لَنَآ أَن نَّتَكَلَّمَ بِهَٰذَا سُبۡحَٰنَكَ هَٰذَا بُهۡتَٰنٌ عَظِيمٞ ١٦
English translation (Saheeh International)
And why, when you heard it, did you not say, "It is not for us to speak of this. Exalted are You, [O Allāh]; this is a great slander"?
Brief commentary
Why did you not say when you heard this slander: “It is not right for us to talk about this gross matter. Purity belongs to You, our Lord. This slander which they accused the Mother of the Believers of is a great lie”?
