“The likeness of the five prayers are like a river, fresh and deep, beside the door of any of you, into which he plunges five times every day, and what do you think that leaves of his uncleanness?” They replied, “Not anything!” He said, “So the five prayers remove sins as water removes dirt.”
“The Prescribed prayer is like a balance: whoever pays in full will receive in full.”
IbnMas‘ud and Salman said. “The prayer is a measure: so, whoever gives in full will receive in full, and whoever gives light measure—well, he knows what Allah said about those giving light measure!” (Qur’an, 83/1).
