Machine translationRead the Arabic original
The Shaykh : For this reason, we say: If a person deliberately leaves off the prayer until its time has passed without an excuse, his prayer is not accepted from him, even if he prays a thousand times. Pay attention to this, O young man.
If a person leaves off the prayer until its time has passed deliberately without an excuse and then prays it, his prayer is not accepted, even if he prays it a thousand times; it is rejected.
But if he says: "By Allah, I slept in late, and instead of setting the alarm for three-thirty, I set it for seven-thirty after the sun had risen, deliberately, and then I got up and prayed."
Is his prayer valid? No, it is not valid.
