عَنْ أَبِي طُعْمَةَ أَنَّهُ قَالَ: كُنْتُ عِنْدَ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُ إِذْ جَاءَهُ رَجُلٌ، فَقَالَ: يَا أَبَا عَبْدِ الرَّحْمَنِ إِنِّي أَقْوَى عَلَى الصِّيَامِ فِي السَّفَرِ، فَقَالَ ابْنُ عُمَرَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقُولُ: ((مَنْ لَمْ يَقْبَلْ رُخْصَةَ اللَّهِ كَانَ عَلَيْهِ مِنَ الْإِثْمِ مِثْلُ جِبَالِ عَرَفَةَ))
Abu Ta’mah narrates: He says, I was present with Sayyiduna Abdullah bin Umar (may Allah be pleased with them). A man came and said: O Abu Abdur Rahman! I have the strength to fast while traveling (so should I fast)? Sayyiduna Abdullah bin Umar (may Allah be pleased with them) said: I heard the Messenger of Allah (peace and blessings be upon him) say: Whoever does not accept the concession granted by Allah, he will receive sin equal to the mountains of Arafah.
