That the Messenger of Allah ﷺ said: “Allah is not too shy to tell the truth,” three times. “Do not have intercourse with women in their buttocks.” (Using translation from Ibn Mājah 1924)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ «إِنَّ اللهَ لَا يَسْتَحْيِي مِنَ الْحَقِّ لَا تَأْتُوا النِّسَاءَ فِي أَدْبَارِهِنَّ»
