[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»
