Bulugh al-Maram 673
Fasting
وَعَنْ حَمْزَةَ بْنِ عَمْرٍو الْأَسْلَمِيِّ رِضَى اَللَّهُ عَنْهُ; أَنَّهُ قَالَ: { يَا رَسُولَ اَللَّهِ! أَجِدُ بِي قُوَّةً عَلَى اَلصِّيَامِ فِي اَلسَّفَرِ, فَهَلْ عَلَيَّ جُنَاحٌ? فَقَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم - هِيَ رُخْصَةٌ مِنَ اَللَّهِ, فَمَنْ أَخَذَ بِهَا فَحَسَنٌ, وَمَنْ أَحَبَّ أَنْ يَصُومَ فَلَا جُنَاحَ عَلَيْهِ } رَوَاهُ مُسْلِمٌ [1] .
Hamzah bin ’Amro Al-Aslami (RAA) narrated, ‘I said to the Messenger of Allah (ﷺ) ‘O Messenger of Allah (ﷺ)! I find within me the strength to fast while traveling. Would there be any blame upon me if I were to do so?’ The Messenger of Allah (ﷺ) said to him, "It is a concession from Allah. Whoever takes it has done well. Whoever likes to fast, there is no blame upon him."Related by Muslim.
