Hadith 1939

نا بُنْدَارٌ ، نا أَبُو عَاصِمٍ ، نا زَمْعَةُ ، عَنْ سَلَمَةَ بْنِ وَهْرَامَ ، عَنْ عِكْرِمَةَ ، عَنِ ابْنِ عَبَّاسٍ ، عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، قَالَ : " اسْتَعِينُوا بِطَعَامِ السَّحَرِ عَلَى صِيَامِ النَّهَارِ , وَبِقَيْلُولَةِ النَّهَارِ عَلَى قِيَامِ اللَّيْلِ "
Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates from the Noble Prophet that he (peace and blessings be upon him) said: "Seek help for the fast of the day by eating the pre-dawn meal (suhoor), and seek help for standing in prayer at night by taking a midday nap during the day."
