Prayer (Kitab Al-Salat)
2/143. Chapter:
The One Who Did Not Recite The Faithah In His Prayer
Sunan Abi Dawud
حَدَّثَنَا ابْنُ بَشَّارٍ، حَدَّثَنَا يَحْيَى، حَدَّثَنَا جَعْفَرٌ، عَنْ أَبِي عُثْمَانَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ أَمَرَنِي رَسُولُ اللَّهِ صلى الله عليه وسلم أَنْ أُنَادِيَ أَنَّهُ لاَ صَلاَةَ إِلاَّ بِقِرَاءَةِ فَاتِحَةِ الْكِتَابِ فَمَا زَادَ .
Abu hurairah said: The Messenger of Allah (ﷺ) commanded me to announce that prayer is not valid but with the recitation of Fatihat al-kitab and something more.
