«أحب الكلام إلى الله تعالى ما اصطفاه الله لملائكته: سبحان ربي وبحمده سبحان ربي وبحمده سبحان ربي وبحمده»
The Prophet (peace and blessings be upon him) said:
"The most beloved speech to Allah Almighty is that which Allah Almighty has chosen for His angels: Subhana Rabbi wa bihamdihi, Subhana Rabbi wa bihamdihi, Subhana Rabbi wa bihamdihi (Glory be to my Lord and praise be to Him)."
