Abu Hurairah said:

"I heard the Messenger of Allah say" 'Whoever spends on a pair of things in the cause of Allah, he will be called from the gates of Paradise: O slave of Allah, this is good for you. Paradise had (several) gates. Whoever is one of the people of Salah, he will be called from the gate of prayer. Whoever is one of the people of Jihad, will be called from the gate of Jihad. Whoever is one of the people of charity will be called from the gate of charity. And whoever is one of the people of fasting will be called from the gate of Ar-Rayyan." Abu Bakr said: "Is there any need for anyone to be called from all of these gates? Will anyone be called from all of them, O Messenger of Allah?" He said: "Yes, and I hope that you will be among them."
