Messenger of Allah ﷺ said, "When night falls from this side and the day vanishes from this side and the sun sets, then the fasting person should break his fast."  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا أَقْبَلَ اللَّيْلُ مِنْ هَا هُنَا وَأَدْبَرَ النَّهَارُ مِنْ هَا هُنَا وَغَرَبَتِ الشَّمْسُ فَقَدْ أَفْطَرَ الصَّائِمُ  

When the night approaches and the day retreates and the sun sinks down, then the observer of the fast should break it. Ibn Numair made no mention of the word" then".  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا أَقْبَلَ اللَّيْلُ وَأَدْبَرَ النَّهَارُ وَغَابَتِ الشَّمْسُ فَقَدْ أَفْطَرَ الصَّائِمُ لَمْ يَذْكُرِ ابْنُ نُمَيْرٍ فَقَدْ  

The Messenger of Allah said: "When the night advances and the day retreats, and the sun is hidden, then the fast is to be broken."  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا أَقْبَلَ اللَّيْلُ وَأَدْبَرَ النَّهَارُ وَغَابَتِ الشَّمْسُ فَقَدْ أَفْطَرْتَ قَالَ وَفِي الْبَابِ عَنِ ابْنِ أَبِي أَوْفَى وَأَبِي سَعِيدٍ  

ʿWhen night comes and day departs and the sun sets, the fasting person may break his fast.”  

أَنَّ النَّبِيَّ ﷺ قَالَ إِذَا أَقْبَلَ اللَّيْلُ وَأَدْبَرَ النَّهَارُ وَغَرَبَتِ الشَّمْسُ فَقَدْ أَفْطَرَ الصَّائِمُ
