This Hadith affirms that man's actions carry weight. On the Day of Judgement, his actions will be cast into the Balance. At that time Allah will endow these actions with weight, or according to some scholars, those 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. This discussion apart, when actions will be cast into the Balance, the formula mentioned in the Hadith, the utterance of which is very easy, will prove weighty. Every Muslim should make it a practice to repeat them frequently.
