Muwatta Imam Malik (Riwayat Ibn al-Qasim)

And with this (chain of narration, it is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him) that the Prophet, peace and blessings be upon him, said: "Whoever spends two things (a pair) in the way of Allah, it will be said to him in Paradise: O servant of Allah! This (door) is better. The one who used to pray will be called from the door of prayer, the one who used to strive (in jihad) will be called from the door of jihad, the one who used to give charity will be called from the door of charity, and the one who used to fast will be called from the door of al-Rayyan (the door for those who fast)." Abu Bakr al-Siddiq, may Allah be pleased with him, said: "The one who is called from these doors will have no further need, but will there be anyone who will be called from all these doors?" The Prophet, peace and blessings be upon him, said: "Yes! And I hope that you will be among those (who will be called from all these doors)."
