وَعَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «لَا يَنْظُرُ اللَّهُ عَزَّ وَجَلَّ إِلَى رَجُلٍ أَتَى رَجُلًا أَوِ امْرَأَةً فِي دُبُرِهَا» . رَوَاهُ التِّرْمِذِيُّ وَقَالَ: هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ
[Ibn ‘Abbas] reported God’s Messenger as saying, “God who is great and glorious will not look at a man who has intercourse with a man or a woman through the anus." Tirmidhi transmitted it, saying; this is a hasan gharib tradition.
