Question
What is the authenticity of the Prophet's supplication in bowing and prostration by saying: 'Subbuhun Quddus Rabb al-Mala'ikati wa al-Ruh'?
Answer
I say, and with God's success: It is established in Sahih Muslim and others from Aisha – may God be pleased with her – that the Prophet (peace be upon him) used to say in his bowing and prostration: "Glory is to You, O God, and praise is Yours; blessed is Your name, and exalted is Your majesty; there is no deity but You." And God knows best.
