وَعَن عبد الله بن عَبَّاس
أَنَّهُ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُعَلِّمُنَا التَّشَهُّدَ كَمَا يُعَلِّمُنَا السُّورَةَ مِنَ الْقُرْآنِ فَكَانَ يَقُولُ: «التَّحِيَّاتُ الْمُبَارَكَاتُ الصَّلَوَاتُ الطَّيِّبَاتُ لِلَّهِ السَّلَامُ عَلَيْكَ أَيُّهَا النَّبِيُّ وَرَحْمَةُ اللَّهِ وَبَرَكَاتُهُ السَّلَامُ عَلَيْنَا وَعَلَى عِبَادِ اللَّهِ الصَّالِحِينَ أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَأَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ».
رَوَاهُ مُسْلِمٌ وَلَمْ أَجِدْ فِي الصَّحِيحَيْنِ وَلَا فِي الْجَمْعِ بَين الصَّحِيحَيْنِ: «سَلام عَلَيْك» و «سَلام عَلَيْنَا» بِغَيْرِ أَلْفٍ وَلَامٍ وَلَكِنْ
God’s Messenger used to teach us the tashahhud just as he would teach us a sura of the Qur’an, and would say, “The blessed adorations of the tongue, acts of worship and all good things are due to God. Peace be upon you, O Prophet, and God’s mercy and blessings. Peace be upon us and upon God’s upright servants. I testify that there is no god but God, and I testify that Muhammad is God’s Messenger.” Muslim transmitted it.
In the two Sahihs and in al-Jam bain as-Sahihain I did not find “Peace be upon you” and “Peace be upon us” without the definite article, but the author of al-Jami transmitted it that way from Tirmidhi.
