Muwatta Malik 492
موطأ مالك#492SahihThese are the words of a Successor — the generation after the Companions — not of the Prophet ﷺ.
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عُمَارَةَ بْنِ صَيَّادٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، أَنَّهُ سَمِعَهُ يَقُولُ فِي الْبَاقِيَاتِ الصَّالِحَاتِ إِنَّهَا قَوْلُ الْعَبْدِ اللَّهُ أَكْبَرُ وَسُبْحَانَ اللَّهِ وَالْحَمْدُ لِلَّهِ وَلاَ إِلَهَ إِلاَّ اللَّهُ وَلاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ .
Yahya related to me from Malik that Umara ibn Sayyad had heard Said ibn al Musayyab say about abiding good deeds that they were a slave's saying 'Allah is greater' (Allahu akbar) and 'Glory be to Allah' (Subahana'llah) and 'Praise be to Allah' (al-hamdu lillah) and 'There is no god but Allah and there is no power and no strength except by Allah.' (La ilaha illa'llah wa la hawla wa la quwwata illa bi'llah)
