[Machine] We were with the Messenger of Allah ﷺ on a journey, then we camped. He called for ablution (wudu) and performed it. Then the call to prayer was announced and he led the people in prayer. When he finished his prayer, he saw a man who had not prayed with the people, so the Messenger of Allah ﷺ said to him, "What prevented you, O so-and-so, from praying with the people?" He replied, "O Messenger of Allah, I was in a state of major ritual impurity (junub) and had no water." The Messenger of Allah ﷺ said, "Then perform dry ablution (tayammum) as it is sufficient for you."  

كُنَّا مَعَ رَسُولِ اللَّهِ ﷺ فِي سَفَرٍ ثُمَّ نَزَلَ فَدَعَا بِوَضُوءٍ فَتَوَضَّأَ ثُمَّ نُودِيَ بِالصَّلَاةِ فَصَلَّى بِالنَّاسِ فَلَمَّا انْفَتَلَ مِنْ صَلَاتِهِ إِذَا هُوَ بِرَجُلٍ مُعْتَزِلٍ لَمْ يُصَلِّ فِي الْقَوْمِ فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ «مَا مَنَعَكَ يَا فُلَانُ أَنْ تُصَلِّيَ فِي الْقَوْمِ؟» فَقَالَ يَا رَسُولَ اللَّهِ أَصَابَتْنِي الجَنَابَةُ وَلَا مَاءَ فَقَالَ رَسُولُ اللَّهِ ﷺ «عَلَيْكَ بِالصَّعِيدِ فَإِنَّهُ يَكْفِيكَ»  

[Machine] Two men went on a journey. When prayer time came, they did not have water with them. So they performed Tayammum on clean ground and prayed. Later, they found water during the appropriate time. One of them repeated his prayer with ablution, while the other did not repeat it. Then they came to the Messenger of Allah ﷺ and narrated what had happened. He said to the one who did not repeat his prayer, "You have followed the Sunnah and your prayer is accepted." And he said to the one who performed ablution and repeated his prayer, "You will have double the reward."  

خَرَجَ رَجُلَانِ فِي سَفَرٍ فَحَضَرَتْهُمَا الصَّلَاةُ وَلَيْسَ مَعَهُمَا مَاءٌ فَتَيَمَّمَا صَعِيدًا طَيِّبًا فَصَلَّيَا ثُمَّ وَجَدَا الْمَاءَ بَعْدُ فِي الْوَقْتِ فَأَعَادَ أَحَدُهُمَا الصَّلَاةَ بِوُضُوءٍ وَلَمْ يُعِدِ الْآخَرُ ثُمَّ أَتَيَا رَسُولَ اللَّهِ ﷺ فَذَكَرَا ذَلِكَ فَقَالَ لِلَّذِي لَمْ يُعِدْ «أَصَبْتَ السُّنَّةَ وَأَجْزَأتْكَ صَلَاتُكَ» وَقَالَ لِلَّذِي تَوَضَّأَ وَأَعَادَ «لَكَ الْأَجْرُ مَرَّتَيْنِ»
