What is the ruling on praying the Fajr prayer upon waking from sleep?

Question:
He says: I am a young man upright in the command of Allah, and I pray all the obligatory prayers in the mosque, except for the Fajr prayer, which I pray at home until I wake up. What is the ruling?

Answer:
Your saying that you are an upright man is self-praise. May Allah guide you. It is not permissible for a person to praise himself and say, "I am upright, I am righteous, I am a believer." This is not permissible because it is self-praise, and Allah the Exalted says: Second, your absence from the Fajr prayer is a crime. You left, meaning you left the congregational prayer.
This is a major crime, because it is not permissible to leave the congregational prayer, neither for Fajr nor for any other prayer. It is obligatory to pray in congregation with the Muslims for all five prayers. The Prophet (peace and blessings be upon him) intended to burn the houses of those who lagged behind in the congregational prayer because of the greatness of their crime, that they isolated themselves from the Muslims and left the congregational prayer. He did not grant a dispensation for leaving the congregation, not even for the blind man who complained to him. He did not grant him a dispensation. He said, "Do you hear the call to prayer?"
He said, "Yes." He said, "Answer his call by responding to the call, which is attending the prayer." And he said, "There is no prayer." He, peace and blessings be upon him, said: So it is not permissible to leave the congregational prayer, neither in Fajr nor in any other prayer.
