إِذْ تَلَقَّوْنَهُۥ بِأَلْسِنَتِكُمْ وَتَقُولُونَ بِأَفْوَاهِكُم مَّا لَيْسَ لَكُم بِهِۦ عِلْمٌۭ وَتَحْسَبُونَهُۥ هَيِّنًۭا وَهُوَ عِندَ ٱللَّهِ عَظِيمٌۭ
When ye welcomed it with your tongues, and uttered with your mouths that whereof ye had no knowledge, ye counted it a trifle. In the sight of Allah it is very great.

Sahih al-Bukhari
Hajj (Pilgrimage)
Chapter: The visit (of the Ka'bah) to perform (Tawaf-al-Ifada) on the Day of Nahr
Narrated `Aisha:
We performed Hajj with the Prophet (ﷺ) and performed Tawaf-al-ifada on the Day of Nahr (slaughtering). Safiya got her menses and the Prophets desired from her what a husband desires from his wife. I said to him, "O Allah's Messenger (ﷺ)! She is having her menses." He said, "Is she going to detain us?" We informed him that she had performed Tawaf-al-Ifada on the Day of Nahr. He said, "(Then you can) depart."
