Abu Huraira, may Allah be pleased with him, reported that the Messenger of Allah, Sallallahu alaihi Wasallam, said :--

 

  "There are two statements that are light for the tongue

   to remember (recite), heavy in the scale and are dear to

   the Merciful : 'SUBHANALLAHI WA BIHAMDIHI, SUBHANALLAHIL

   AZIM (Glory be to Allah and His is the Praise, and Allah, the Greatest

   is free from imperfection) "--Bukhari and Muslim.

 This Hadith affirms that man' s actions carry weight, and on the Day of Judgement his actions will be cast into the Balance. At that time Allah endow these actions with weight, or records which register man's actions will be weighed. This is quite possible for the reason that Almighty Allah is capable of weighing things without even their physical form.

  

When actions will be cast into the Balance, the formula mentioned in the above hadith, the utterance of which is very easy, will prove weighty. Every Muslim should make it a practice to repeat them frequently. 

Best Wishes.
