HAKIM 520:
from Rubayḥ b. ʿAbd al-Raḥman b. Abū Saʿīd al-Khudrī from his father from his grandfather —
[Machine] The Messenger of Allah ﷺ said, "There is no prayer for someone who does not have ablution, and there is no ablution for someone who does not mention the name of Allah upon it." Ali ibn Bundar Az-Zahid informed me, narrating from Umar ibn Muhammad ibn Jubayr, narrating from Abu Bakr Al-Athram, who said, "I heard Ahmad ibn Hanbal being asked about someone who performs ablution but does not mention (the name of Allah). Ahmad replied, 'The best that can be said about this hadith is what Kathir ibn Zayd has narrated.'"

عن ربيح بن عبد الرحمن بن ابو سعيد الخدري عن أبيه عن جده —
قَالَ رَسُولُ اللَّهِ ﷺ «لَا صَلَاةَ لِمَنْ لَا وُضُوءَ لَهُ وَلَا وُضُوءَ لِمَنْ لَمْ يَذْكُرِ اسْمَ اللَّهِ عَلَيْهِ» فَأَخْبَرَنِي عَلِيُّ بْنُ بُنْدَارٍ الزَّاهِدُ ثنا عُمَرُ بْنُ مُحَمَّدِ بْنِ جُبَيْرٍ ثنا أَبُو بَكْرٍ الْأَثْرَمُ وَقَالَ سَمِعْتُ أَحْمَدَ بْنَ حَنْبَلٍ وَسُئِلَ عَمَّنْ يَتَوَضَّأُ وَلَا يُسَمِّي فَقَالَ أَحْمَدُ أَحْسَنُ مَا يُرْوَى فِي هَذَا الْحَدِيثِ كَثِيرُ بْنُ زَيْدٍ
