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.)
Muwatta Malik Book 15, Hadith 25
