Prayer (Kitab Al-Salat)
2/128. Chapter:
The Supplication With Which The Prayer Should Be Started
Sunan Abi Dawud
حَدَّثَنَا عَمْرُو بْنُ عُثْمَانَ، حَدَّثَنَا شُرَيْحُ بْنُ يَزِيدَ، حَدَّثَنِي شُعَيْبُ بْنُ أَبِي حَمْزَةَ، قَالَ قَالَ لِي مُحَمَّدُ بْنُ الْمُنْكَدِرِ وَابْنُ أَبِي فَرْوَةَ وَغَيْرُهُمَا مِنْ فُقَهَاءِ أَهْلِ الْمَدِينَةِ فَإِذَا قُلْتَ أَنْتَ ذَاكَ فَقُلْ " وَأَنَا مِنَ الْمُسْلِمِينَ " . يَعْنِي قَوْلَهُ " وَأَنَا أَوَّلُ الْمُسْلِمِينَ " .
Shu’aib b. Abi Hamzah said: Ibn al-Munkadir, Ibn Abi Farwah and a number of jurists of Madina said to me: When you recite the supplication “I am first of the Muslims,” say instead; “I am one of the Muslims”.
