"The following is the testament of Rabee' bin Khuthaym, in the name of Allah, the Most Merciful, the Most Compassionate. This is what Rabee' bin Khuthaym has advised, and I bear witness to Allah, who suffices as a witness and rewarder for His righteous servants. Verily, I am pleased with Allah as my Lord, Islam as my religion, and Muhammad ﷺ as a prophet. Indeed, I command myself and those who obey me to worship Allah among the worshippers, to praise Him among those who praise Him, and to sincerely advise the Muslim community." – Sound Chain

كَتَبَ الرَّبِيعُ بْنُ خُثَيْمٍ وَصِيَّتَهُ بِسْمِ اللَّهِ الرَّحْمَنِ الرَّحِيمِ هَذَا مَا أَوْصَى بِهِ الرَّبِيعُ بْنُ خُثَيْمٍ وَأَشْهَدَ اللَّهَ عَلَيْهِ وَكَفَى بِاللَّهِ شَهِيدًا وَجَازِيًا لِعِبَادِهِ الصَّالِحِينَ وَمُثِيبًا فَإِنِّي رَضِيتُ بِاللَّهِ رَبًّا وَبِالْإِسْلَامِ دِينًا وَبِمُحَمَّدٍ ﷺ نَبِيًّا وَإِنِّي آمُرُ نَفْسِي وَمَنْ أَطَاعَنِي أَنْ نَعْبُدَ اللَّهَ فِي الْعَابِدِينَ وَنَحْمَدَهُ فِي الْحَامِدِينَ وَأَنْ نَنْصَحَ لِجَمَاعَةِ الْمُسْلِمِينَ – إسناده صحيح
