It was narrated from Qais bin 'Asim that he accepted Islam, and the Prophet commanded him to perform Ghusl with water and lotus leaves. (Using translation from Nasāʾī 188)  

أَنَّهُ أَسْلَمَ «فَأَمَرَهُ النَّبِيُّ ﷺ أَنْ يَغْتَسِلَ بِمَاءٍ وَسِدْرٍ»  

[Machine] That Muhammad is his slave and messenger. O Muhammad, I swear by Allah, there was never a face on earth that I disliked more than your face, but now your face has become the most beloved of all faces to me. By Allah, there was never a religion that I disliked more than your religion, but now your religion has become the most beloved of all religions to me. By Allah, there was never a land that I disliked more than your land, but now your land has become the most beloved of all lands to me. And indeed, your cavalry has taken me while I desire to perform Umrah. What do you think?" So the Messenger of Allah ﷺ gave him the glad tidings and commanded him to perform Umrah.  

أَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ يَا مُحَمَّدُ وَاللهِ مَا كَانَ عَلَى الْأَرْضِ وَجْهٌ أَبْغَضَ إِلَيَّ مِنْ وَجْهِكَ فَقَدْ أَصْبَحَ وَجْهُكَ أَحَبَّ الْوُجُوهِ كُلِّهَا إِلَيَّ وَوَاللهِ مَا كَانَ دِينٌ أَبْغَضَ إِلَيَّ مِنْ دَيْنِكَ فَأَصْبَحَ دَيْنُكَ أَحَبَّ الدِّينِ كُلِّهِ إِلَيَّ وَوَاللهِ مَا كَانَ مِنْ بَلَدٍ أَبْغَضَ إِلَيَّ مِنْ بَلَدِكَ فَأَصْبَحَ بَلَدُكَ أَحَبَّ الْبِلَادِ كُلِّهَا إِلَيَّ وَإِنَّ خَيْلَكَ أَخَذَتْنِي وَأَنَا أُرِيدَ الْعُمْرَةَ فَمَاذَا تَرَى؟ «فَبَشَّرَهُ رَسُولُ اللهِ ﷺ وَأَمَرَهُ أَنْ يَعْتَمِرَ»
