Ibn Hajar said, “The majority of scholars, among them Malik, Al-Shafi’i, and Abu Hanifa, maintain that fasting is better for those who have strength and will not experience difficulty. Many of them said it is better to break the fast as a concession, which is the opinion of Al-Awza’i, Ahmad, and Ishaq.”

عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا أَنَّهَا قَالَتْ سَأَلَ حَمْزَةُ بْنُ عَمْرٍو الْأَسْلَمِيُّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ الصِّيَامِ فِي السَّفَرِ فَقَالَ إِنْ شِئْتَ فَصُمْ وَإِنْ شِئْتَ فَأَفْطِرْ

قال ابن حجر وَذَهَبَ أَكْثَرُ الْعُلَمَاءِ وَمِنْهُمْ مَالِكٌ وَالشَّافِعِيُّ وَأَبُو حَنِيفَةَ إِلَى أَنَّ الصَّوْمَ أَفْضَلُ لِمَنْ قَوِيَ عَلَيْهِ وَلَمْ يَشُقَّ عَلَيْهِ وَقَالَ كَثِيرٌ مِنْهُمْ الْفِطْرُ أَفْضَلُ عَمَلًا بِالرُّخْصَةِ وَهُوَ قَوْلُ الْأَوْزَاعِيِّ وَأَحْمَدَ وَإِسْحَاقَ
