Hadith 1:85
Narrated Talq bin ‘Ali (rad):
A man said: “I touched my penis” or he said, “Does a man who touch his penis during the prayer should perform Wudu (ablution)?” The Prophet (ﷺ) replied, “No, it is only a part of your body”. [Reported by Al-Khamsa. Ibn Hibban graded it Sahih (sound).
وَعَنْ طَلْقِ بْنِ عَلِيٍّ - رضى الله عنه - قَالَ: { قَالَ رَجُلٌ: مَسَسْتُ ذَكَرِي أَوْ قَالَ اَلرَّجُلُ يَمَسُّ ذَكَرَهُ فِي اَلصَّلَاةِ, أَعَلَيْهِ وُضُوءٍ ? فَقَالَ اَلنَّبِيُّ - صلى الله عليه وسلم -"لَا, إِنَّمَا هُوَ بَضْعَةٌ مِنْكَ } أَخْرَجَهُ اَلْخَمْسَةُ, وَصَحَّحَهُ اِبْنُ حِبَّان َ (91)
