Is there a word about what some people do, which is sleeping for most of the day during Ramadan?

Question:
The questioner asks: Is there a word about what some people do, which is sleeping for most of the day during Ramadan, and how was the guidance of the Salaf regarding sleep in the month of Ramadan?

Answer:
Excessive sleep in the month of Ramadan is a loss. It is obligatory for a person to sleep only as much as he needs. He should spend the rest of the time in the remembrance of Allah, reciting the Qur'an, and performing acts of obedience in this noble month. He should sleep at night. He should sleep at night only as much as he needs to get his rest, especially sleeping at the beginning of the night.
Sleeping at the beginning of the night is better than sleeping at the end of the night, so that he may get his rest and rise at the end of the night energetic for the tahajjud prayer and the Fajr prayer. So he sleeps at the beginning of the night, and he also sleeps in the middle of the day for the qaylulah (midday nap). He sleeps in the middle of the day after the Zuhr prayer, between Zuhr and 'Asr.
So that he may prepare for the tarawih prayer and for performing the obligatory prayers at their times in congregation. He sleeps at the beginning of the night and also sleeps in the qaylulah in the middle of the day, and this is sufficient. As for sleeping the whole day, staying up the whole night, and sleeping the whole day, this is a great loss. The night passes for him and the day passes for him without any benefit.
