Musnad Ahmad 3921 — Musnad of Abdullah ibn Mas'ud

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) taught us the words of Tashahhud in prayer: «التَّحِيَّاتُ لِلّٰهِ وَالصَّلَوَاتُ وَالطَّيِّبَاتُ السَّلَامُ عَلَيْكَ أَيُّهَا النَّبِيُّ وَرَحْمَةُ اللّٰهِ وَبَرَكَاتُهُ السَّلَامُ عَلَيْنَا وَعَلَى عِبَادِ اللّٰهِ الصَّالِحِينَ أَشْهَدُ أَنْ لَا إِلٰهَ إِلَّا اللّٰهُ وَأَشْهَدُ أَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ» The translation of which is: “All verbal, physical, and bodily acts of worship are for Allah alone. O Prophet (peace and blessings of Allah be upon him)! Peace be upon you, and may Allah’s mercy and blessings descend upon you. Peace be upon us and upon the righteous servants of Allah. I bear witness that there is no deity except Allah, and that Muhammad (peace and blessings of Allah be upon him) is Allah’s servant and His Messenger.”
