[Machine] To lead the people who perform Tayammum (dry ablution) and are in a state of purification. This is a chain of narration that is not supported by valid evidence.  

أَنْ يَؤُمَّ الْمُتَيَمِّمُ الْمُتَوَضِّئِينَ وَهَذَا إِسْنَادٌ لَا تَقُومُ بِهِ الْحُجَّةُ  

[Machine] "And Abu Abdullah (Imam Ahmad) narrated to us, from Abu Bakr, from Abdullah, from Ishaq, from Ibn Wahb, from Muaawiya ibn Salih, from Al-Ala' ibn Al-Harith, from Nafi', who said: Ibn Umar experienced sexual defilement during a journey, so he performed ablution with tayammum (dry ablution). He then ordered me to lead the prayer, and I was in a state of ritual purification (wudu'). This act is recommended (Mustahabb) and it has been narrated that there is a weak hadith regarding it."  

وَأَخْبَرَنَا أَبُو عَبْدِ اللهِ أنا أَبُو بَكْرٍ أنا عَبْدُ اللهِ ثنا إِسْحَاقُ ثنا ابْنُ وَهْبٍ ثنا مُعَاوِيَةُ بْنُ صَالِحٍ عَنِ الْعَلَاءِ بْنِ الْحَارِثِ عَنْ نَافِعٍ قَالَ أَصَابَ ابْنَ عُمَرَ جَنَابَةٌ فِي سَفَرٍ فَتَيَمَّمَ فَأَمَرَنِي فَصَلَّيْتُ بِهِ وَكُنْتُ مُتَوَضِّئًا وَهَذَا مَحْمُولٌ عَلَى الِاسْتِحْبَابِ وَرُوِيَ فِيهِ حَدِيثٌ ضَعِيفٌ  

[Machine] The Messenger of Allah ﷺ said: "The one who performs Tayammum (dry ablution) should not lead the ones who have performed Wudu (ritual washing)." Ali said: "The chain of narration for this hadith is weak."  

قَالَ رَسُولُ اللهِ ﷺ لَا يَؤُمُّ الْمُتَيَمِّمُ الْمُتَوَضِّئِينَ قَالَ عَلِيٌّ إِسْنَادُهُ ضَعِيفٌ
