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

Amir b. Sa'd b. Abu Waqqas reported Allah's Messenger (ﷺ) as saying:He who ate seven 'ajwa' dates in the morning, poison and magic will not harm him on that day

This hadith has been reported on the authority of Ibn Hashim with the same chain of transmitters but with a slight variation of wording
