عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((السَّحُورُ أَكْلَةٌ بَرَكَةٌ فَلَا تَدَعُوهُ وَلَوْ أَنْ يَجْرَعَ أَحَدُكُمْ جَرْعَةً مِنْ مَاءٍ، فَإِنَّ اللَّهَ عَزَّ وَجَلَّ وَمَلَائِكَتَهُ يُصَلُّونَ عَلَى الْمُتَسَحِّرِينَ))
Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: The pre-dawn meal (suhoor) is blessed, so do not abandon it, even if you only take a sip of water. Indeed, Allah the Exalted and the angels send mercy upon those who partake in suhoor. That is, Allah sends mercy and the angels pray for the descent of mercy.
