Musnad Ahmad

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said these words in response to a man: «إِنَّ الْحَمْدَ لِلّٰهِ نَحْمَدُهُ وَنَسْتَعِينُهُ مَنْ يَهْدِهِ اللّٰهُ فَلَا مُضِلَّ لَهُ وَمَنْ يُضْلِلْ فَلَا هَادِيَ لَهُ وَأَشْهَدُ أَنْ لَا إِلٰهَ إِلَّا اللّٰهُ وَحْدَهُ لَا شَرِيكَ لَهُ وَأَشْهَدُ أَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ» "All praise is due to Allah, we praise Him and seek help from Him. Whomever Allah guides, none can misguide him, and whomever He lets go astray, none can guide him. I bear witness that there is no deity except Allah, He is alone, He has no partner, and I also bear witness that Muhammad (peace and blessings be upon him) is Allah's servant and His Messenger."
