عَنْ عَمْرِو بْنِ الْعَاصِ رَضِيَ اللَّهُ عَنْهُ أَنَّهُ قَالَ: لَمَّا بَعَثَهُ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ عَامَ ذَاتِ السَّلَاسِلِ قَالَ: احْتَلَمْتُ فِي لَيْلَةٍ بَارِدَةٍ شَدِيدَةِ الْبَرْدِ فَأَشْفَقْتُ إِنِ اغْتَسَلْتُ أَنْ أَهْلِكَ فَتَيَمَّمْتُ ثُمَّ صَلَّيْتُ بِأَصْحَابِي صَلَاةَ الصُّبْحِ، قَالَ: فَلَمَّا قَدِمْنَا عَلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ذَكَرْتُ ذَلِكَ لَهُ، فَقَالَ: يَا عَمْرُو! صَلَّيْتَ بِأَصْحَابِكَ وَأَنْتَ جُنُبٌ؟ قَالَ: قُلْتُ: نَعَمْ يَا رَسُولَ اللَّهِ! إِنِّي احْتَلَمْتُ فِي لَيْلَةٍ بَارِدَةٍ شَدِيدَةِ الْبَرْدِ فَأَشْفَقْتُ إِنِ اغْتَسَلْتُ أَنْ أَهْلِكَ وَذَكَرْتُ قَوْلَ اللَّهِ عَزَّ وَجَلَّ {وَلَا تَقْتُلُوا أَنْفُسَكُمْ إِنَّ اللَّهَ كَانَ بِكُمْ رَحِيمًا} فَتَيَمَّمْتُ ثُمَّ صَلَّيْتُ فَضَحِكَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ وَلَمْ يَقُلْ شَيْئًا
Sayyiduna Amr bin al-As (may Allah be pleased with him) says: When the Messenger of Allah (peace and blessings be upon him) sent me in the year of Dhat al-Salasil, on a very cold night I had a wet dream. I feared that if I performed ghusl (ritual bath), I would die, so I performed tayammum and led my companions in the Fajr prayer. When we came to the Messenger of Allah (peace and blessings be upon him), I informed him of this matter. He (peace and blessings be upon him) said: O Amr! Did you lead your companions in prayer while you were in a state of janabah (major ritual impurity)? I said: Yes, O Messenger of Allah! I had a wet dream and it was a very cold night. I feared that if I performed ghusl, I would die, and I also remembered Allah Almighty’s statement: “Do not kill yourselves; indeed, Allah is ever Merciful to you.” So I performed tayammum and led them in prayer. Upon hearing this, the Messenger of Allah (peace and blessings be upon him) smiled and said nothing.
