Recommendation to break the fast with rutab (rutabah) dates

The Messenger of Allah ﷺ used to break his fast before praying with some rutabah dates; but if there were no rutabah dates, he had a few fully ripened dates, and if there were no fully ripened dates, he took some mouthfuls of water.

أَنَّهُ سَمِعَ أَنَسَ بْنَ مَالِكٍ يَقُولُ كَانَ رَسُولُ اللَّهِ ﷺ يُفْطِرُ عَلَى رُطَبَاتٍ قَبْلَ أَنْ يُصَلِّيَ فَإِنْ لَمْ تَكُنْ رُطَبَاتٌ فَعَلَى تَمَرَاتٍ فَإِنْ لَمْ تَكُنْ حَسَا حَسَوَاتٍ مِنْ مَاءٍ
