The virtue of the dates of Al-Madinah
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ بْنِ قَعْنَبٍ، حَدَّثَنَا سُلَيْمَانُ، - يَعْنِي ابْنَ بِلاَلٍ - عَنْ عَبْدِ اللَّهِ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ عَامِرِ بْنِ سَعْدِ بْنِ أَبِي وَقَّاصٍ، عَنْ أَبِيهِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " مَنْ أَكَلَ سَبْعَ تَمَرَاتٍ مِمَّا بَيْنَ لاَبَتَيْهَا حِينَ يُصْبِحُ لَمْ يَضُرَّهُ سُمٌّ حَتَّى يُمْسِيَ " .
Amir b. Sa'd b. Abu Waqqas, on the authority of his father, reported Allah's Messenger (ﷺ) having said: He who ate seven dates (of the land situated) between these two lava plains in the morning, no poison will harm him until it is evening.
