1442 - وَقَالَ اَلْبَاقِرُ عَلَيْهِ اَلسَّلاَمُ: «اَلنَّوْمُ أَوَّلَ اَلنَّهَارِ خُرْقٌ وَ اَلْقَائِلَةُ نِعْمَةٌ وَ اَلنَّوْمُ بَعْدَ اَلْعَصْرِ حُمْقٌ وَ اَلنَّوْمُ بَيْنَ اَلْعِشَاءَيْنِ يَحْرِمُ اَلرِّزْقَ.
Hadith.1442 - Al-Baqir (as) said: "Sleeping at the beginning of the day is wastefulness, the nap at midday is a blessing, sleeping after Asr (afternoon prayer) is foolishness, and sleeping between the two night prayers (Maghrib and Isha) deprives one of sustenance."
