Once a man was walking and he read this written on a wall:
'Qull huwa Allah hu ahad, Allah hu samad, Lam yalid Wa lam youlad, Wa lam yakoun lahu koufwan ahad'
So he sat and read it, while he was reading it a man was watching him and came to him and said 'Do you know that you have got at least 470 hasana's (blessings) just for reading this! The person who wrote this on the wall also got 470 hasana's; Even I got 470 hasana's just for redaing thisEven you got (who is reading this) 470 hasana's.
