4892 - وَ فِي خَبَرٍ آخَرَ قَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ : "إِذَا اِدَّعَتِ اَلْمَرْأَةُ عَلَى زَوْجِهَا أَنَّهُ عِنِّينٌ وَ أَنْكَرَ اَلرَّجُلُ أَنْ يَكُونَ كَذَلِكَ فَالْحُكْمُ فِيهِ أَنْ يَقْعُدَ اَلرَّجُلُ فِي مَاءٍ بَارِدٍ فَإِنِ اِسْتَرْخَى ذَكَرُهُ فَهُوَ عِنِّينٌ وَ إِنْ تَشَنَّجَ فَلَيْسَ بِعِنِّينٍ".
Hadith.4892 - In another narration, Imam Jafar ibn Muhammad Al-Sadiq (as) said: "If a woman accuses her husband of being impotent (ʿinnin) and the man denies it, the ruling in this case is that the man should sit in cold water. If his private part becomes relaxed, then he is indeed impotent. But if it becomes tense, then he is not impotent."
