حَدَّثَنَا يَعْقُوبُ قَالَ حَدَّثَنِي أَبِي عَنِ ابْنِ إِسْحَاقَ قَالَ حَدَّثَنِي عَنْ تَشَهُّدِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي وَسَطِ الصَّلَاةِ وَفِي آخِرِهَا عَبْدُ الرَّحْمَنِ بْنُ الْأَسْوَدِ بْنِ يَزِيدَ النَّخَعِيُّ عَنْ أَبِيهِ عَنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ قَالَ عَلَّمَنِي رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ التَّشَهُّدَ فِي وَسَطِ الصَّلَاةِ وَفِي آخِرِهَا فَكُنَّا نَحْفَظُ عَنْ عَبْدِ اللَّهِ حِينَ أَخْبَرَنَا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَلَّمَهُ إِيَّاهُ قَالَ فَكَانَ يَقُولُ إِذَا جَلَسَ فِي وَسَطِ الصَّلَاةِ وَفِي آخِرِهَا عَلَى وَرِكِهِ الْيُسْرَى التَّحِيَّاتُ لِلَّهِ وَالصَّلَوَاتُ وَالطَّيِّبَاتُ السَّلَامُ عَلَيْكَ أَيُّهَا النَّبِيُّ وَرَحْمَةُ اللَّهِ وَبَرَكَاتُهُ السَّلَامُ عَلَيْنَا وَعَلَى عِبَادِ اللَّهِ الصَّالِحِينَ أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَأَشْهَدُ أَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ قَالَ ثُمَّ إِنْ كَانَ فِي وَسَطِ الصَّلَاةِ نَهَضَ حِينَ يَفْرُغُ مِنْ تَشَهُّدِهِ وَإِنْ كَانَ فِي آخِرِهَا دَعَا بَعْدَ تَشَهُّدِهِ مَا شَاءَ اللَّهُ أَنْ يَدْعُوَ ثُمَّ يُسَلِّمَ
مسند امام احمد بن حنبل · Hadith 4382
It was narrated that 'Abdullah ibn Mas'ood said: The Messenger of Allah (PBUH) taught me the tashahhud in the middle 0f the prayer and at the end of it. [The narrator said:] We memorized it from 'Abdullah when he told us that the Messenger of Allah (PBUH) taught it tp him- He said: He used to say, when he sat on his left hip in the nuddle of the prayer and at the end; "All compliments, prayers an d pure words are due to Allah, peace be upon you, O Prophet, and the mercy of Allah and His blessings. Peace be upon us, and upon the righteous slaves of Allah I bear witness that there is no god but Allah, and I bear witness that Muhammad is His slave and Messenger.” Then if it was in the middle of the prayer, he would get up when he finished the tashahhud, and if it was the end of the prayer, he would offer supplication (du'aa') after the prayer as Allah willed he should, then he would say the tasleem.
