He who has a morning meal of seven ‘Ajwah dates will not suffer from any harm that day through poison or magic. (Using translation from Abū Dāʾūd 3876)   

عَنِ النَّبِيِّ ﷺ قَالَ «مَنْ يَتَصَبَّحْ سَبْعَ تَمَرَاتٍ مِنْ عَجْوَةٍ لَمْ يَضُرَّهُ ذَلِكَ الْيَوْمَ سُمٌّ وَلَا سِحْرٌ» قَالَ إِسْحَاقُ فِي حَدِيثِهِ يَعْنِي ذَلِكَ الْيَوْمَ
