Narrated Abû Huraira رضى الله عنه : The Prophet صلى الله عليه وسلم said, "There are two expressions which are very easy for the tongue to say, but they are very heavy in the balance (of deeds) and are very dear to the Beneficent (Allâh), and they are, ' Subhân Allâhi Al-Azîm wa Subhân Allâhi wa bihamdihi .'" [2] ( Sahîh Al-Bukhâri, Hadîth No. 415, Vol. 8 )
