Sayyidina Abu Sa’eed and Abu Hurayrah bore testimony that the Prophet .i-i said: If anyone says
There is no God but Allah and Allah is the Greatest,
then Allah his l..ord attests him, saying.
There is no God but I and I am The Greatest.
And, if he says:
then Allah says,”
‘There is no God but I and I am Alone.” And if he says:
There is no God but Allah Who is Alone and Who has no partner,
then He says, “There is no God but I Who is Alone and I have no partner.” and, if he says:
There is no God but Allah to whom belongs the dominion and to whom belongs all praise,
Then Allah says, There is no God but I. To Me belongs the dominion and to Me belongs all praise.” And, if he says:
There is no God but Allah and there is no power and no might except with Allah,
Then Allah says, There is no God but I and there is no power and no might except with Me. If a person utters these expressions in his illness and dies then the fire will not consume him.
[Ibn e Majah 3784]
