the Messenger of Allah said: "Whoever has dried dates, then let him break the fast with that, and whoever does not, then let him break the fast with water, for indeed water is purifying." (Using translation from Tirmidhī 694)
عَنِ رَسُولِ اللهِ ﷺ قَالَ «مَنْ وَجَدَ تَمْرًا فَلْيُفْطِرْ عَلَيْهِ وَمَنْ لَمْ يَجِدْ تَمْرًا فَلْيُفْطِرْ عَلَى الْمَاءِ فَإِنَّ الْمَاءَ طَهُورٌ»
