Sunan Abi Dawud, Hadith 101

Narrated AbuHurayrah: The Messenger of Allah said: The prayer of a person who does not perform ablution is not valid, and the ablution of a person who does not mention the name of Allah (in the beginning) is not valid.

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا مُحَمَّدُ بْنُ مُوسَى، عَنْ يَعْقُوبَ بْنِ سَلَمَةَ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ لاَ صَلاَةَ لِمَنْ لاَ وُضُوءَ لَهُ وَلاَ وُضُوءَ لِمَنْ لَمْ يَذْكُرِ اسْمَ اللَّهِ تَعَالَى عَلَيْهِ ‏" ‏ ‏.‏
