أَئِنَّكُمْ لَتَأْتُونَ ٱلرِّجَالَ وَتَقْطَعُونَ ٱلسَّبِيلَ وَتَأْتُونَ فِى نَادِيكُمُ ٱلْمُنكَرَ ۖ فَمَا كَانَ جَوَابَ قَوْمِهِۦٓ إِلَّآ أَن قَالُوا۟ ٱئْتِنَا بِعَذَابِ ٱللَّهِ إِن كُنتَ مِنَ ٱلصَّٰدِقِينَ
For come ye not in unto males, and cut ye not the road (for travellers), and commit ye not abomination in your meetings? But the answer of his folk was only that they said: Bring Allah's doom upon us if thou art a truthteller!
Surah Al-Ankaboot(29:29)

Fasting
Chapter: Observing Saum (fast) on the day of 'Arafah.
Narrated Maimuna:
The people doubted whether the Prophet (ﷺ) was fasting on the day of `Arafat or not, so I sent milk while he was standing at `Arafat, he drank it and the people were looking at him.
Sahih al-Bukhari 1989
