Some of the poor people of Madinah approached Rasool Allah (P.B.U.H) and said to him: "The affluent ones perform acts of goodness like freeing slaves, giving charity, performing the Hajj etc., which are beyond our means (as a result, they shall be in possession of greater rewards than us)."
Rasool Allah (P.B.U.H) said: "One, who recites Allahu Akbar (Allah is the Greatest) a hundred times, shall be granted rewards which shall exceed the rewards of freeing one hundred slaves. One, who recites Subhan Allah (Glorious is Allah) a hundred times, shall come to possess rewards better than the rewards associated with the performance of Hajj. Reciting Alhamdulillah (Praise be to Allah) a hundred times is better than giving one hundred fully laden horses as charity in the way of Allah (S.W.T). One, who recites La Ilaha Illallah (There is No God but Allah) a hundred times, shall be of the best of the people on the Day of Judgment."
When the affluent ones of Madinah came to know of this they too began to act upon these recommendations and so the poor ones again approached Rasool Allah (P.B.U.H) and complained: "The affluent ones too have started to act upon your recommendations!"
Hearing their complaint, Rasool Allah (P.B.U.H) remarked: "This is Allah's grace and favour; He grants it to whomsoever He pleases."
