1. Allaah, the Most High, says:
"As for him whose balance (of good deeds) will be heavy, he will live a pleasant life (in Paradise). But, as for him whose balance (of good deeds) will be light, he will have his home in a pit (i.e. Hell)". (Soorah al-Qaari'ah 101:6-7) Abu Hurairah, radiallaahu 'anhu, reports that Allaah's Messenger (saws) said, "Two words are most beloved to the Most Merciful, light upon the tongue and heavy upon the Balance: Subhaanallahi wa bihamdihi and Subhaanallahil 'Adheem." Reported by al-Bukhaaree (Eng. trans. 9/489-490/no.652).
The 'Hadeeth of the Parchment': "Abdullah ibn 'Amr ibn al 'Aas said: I heard Allaah's Messenger (saws) say, "Allaah will take out a man from my Ummah before the creation on the Day of Resurrection and ninety-nine scrolls will be unrolled for him. Each one as long as the eye can see. Then He will say 'Do you deny any of this? Have my watchful scribes wronged you?' He will reply 'No, O my Lord!' So, He (Allaah) will say 'Do you have any excuse (or any good deed)? So he will reply 'No, O my Lord!' So, He (Allaah) will say 'Rather you do possess a good deed with Us and you will not be wronged this Day.' So a parchment is brought containing 'I bear witness that none has the right to be worshipped except Allaah and I bear witness that Muhammad is His Slave and Messenger.' So He (Allaah) will say 'Witness the weighing.' So he will reply 'O my Lord! What is this parchment compared to those great scrolls?' So He (Allaah) will say 'Indeed you will not be wronged.' So the scrolls will be placed on one scale and the parchment on the other scale. So the scrolls will be lighter and the parchment heavier. Nothing will outweigh the name of Allaah." Reported by Ahmad, at-Tirmidhee and Ibn Maajah. Shaikh al-Albaanee declared it saheeh in Saheeh Sunan at-Tirmidhee.
