Will the prayers, fasting, and zakat of one who sleeps through Fajr prayer but observes the other prayers intercede for him in the grave?

Prayer is the most important act by which a servant draws near to his Lord after faith. Allah has prescribed it at specific times, and He has warned those who neglect it or delay it beyond its time with punishment. Therefore, whoever intentionally misses the Fajr prayer and sleeps through it is sinful and deserves punishment, and he will be rewarded for his good deeds and punished for his bad ones. It is obligatory to maintain prayer at its prescribed time by strengthening faith and taking the necessary means. As for someone who is overcome by sleep after taking the necessary means, there is no sin upon him, and he should pray it upon waking up.
