The remaining righteous deeds
The reward for praying a lot is great
On the authority of Abu Hurairah, may God be pleased with him
The Prophet, may God bless him and grant him peace, said to Bilal:
Oh Bilal
Tell me about the most important work you have done in Islam.
For I heard that you were buried before me in Paradise.
He said
I have never done anything I hope for
I have not purified myself completely at any time of the day or night.
Unless I pray, thereby purifying what was decreed for me to pray.
