Arabic (Original)
حَدَّثَنَا زَيْدُ بْنُ الْحُبَابِ حَدَّثَنِي مُعَاوِيَةُ بْنُ صَالِحٍ حَدَّثَنِي السَّفْرُ بْنُ نُسَيْرٍ الْأَزْدِيُّ عَنْ يَزِيدَ بْنِ شُرَيْحٍ الْحَضْرَمِيِّ عَنْ أَبِي أُمَامَةَ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهُ قَالَ لَا يَأْتِي أَحَدُكُمْ الصَّلَاةَ وَهُوَ حَاقِنٌ وَلَا يَؤُمَّنَّ أَحَدُكُمْ فَيَخُصَّ نَفْسَهُ بِالدُّعَاءِ دُونَهُمْ فَمَنْ فَعَلَ فَقَدْ خَانَهُمْ.
English Translation
Zayd ibn al-Hubab told us, Mu'awiyah ibn Salih told me, al-Safr ibn Nusayr al-Azdi told me, from Yazid ibn Shurayh al-Hadrami, from Abu Umamah, from the Prophet, peace and blessings be upon him, that he said: "None of you should come to prayer while needing to relieve himself, and none of you should lead the people in prayer and single himself out with a supplication apart from them -- whoever does so has betrayed them."
