Abu Hurairah (May Allah be pleased with him) reported:
The Messenger of Allah (PBUH) said,
"There are two statements that are light for the tongue
to remember, heavy in the Scales and are dear to the Merciful:
`Subhan-Allahi wa bihamdihi, Subhan-Allahil-Azim
[Glory be to Allah and His is the praise, (and) Allah, the
Greatest is free from imperfection)'.''
[Al-Bukhari and Muslim].
Commentary: 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.
