بِسْمِ اللهِ الرَّحْمنِ الرَّحِيمِ
"It is mentioned, that there is a pillar in front of the Arsh of Allah سبحانه وتعالى, which begins vibrating heavily when a person recites,
لا اله الا الله
'LA ILAHA ILLALAH'
Allah سبحانه وتعالى commands: 'Stop! Be at ease!'
The pillar replies: 'How can I be at ease when the reciter of لا اله الا الله has not been forgiven?'
Then Allah سبحانه وتعالى says to it: 'Stop! I have forgiven the reciter of لا اله الا الله' "
Subhallah! Allah سبحانه وتعالى is so merciful to us! I have heard this hadith before in Taleem and I am sure it is Sahih but unfortunately in the book I'm reading it does not say who narrated it. It is late so I wont look now but Inshallah I will check my other kitabs and will post up who the narrator was.
