The Prophet ﷺ said: “The people will remain upon good as long as they hasten to break the fast.” (al-Bukhārī & Muslim). Break your fast the moment Maghrib enters — with dates or a few sips of water — before praying.
العربية: عن سهل بن سعد رضي الله عنه أنّ رسول الله ﷺ قال: «لا يزال الناس بخير ما عجَّلوا الفِطر». (البخاري ومسلم).
Following the Sunnah in timing is a mercy — don't delay iftar once the time has come.
