[Machine] According to the saying of Allah Almighty, "And indeed, a day with your Lord is like a thousand years of those which you count." [Al-Hajj 47]. So the man asked, "Who are you?" It was mentioned to him that he was a man from such and such people. Ibn Abbas then said, "So what is the duration of a day that is fifty thousand years?" The man replied, "May Allah have mercy on you, I only asked you to inform us." Ibn Abbas said, "There are two days that Allah Almighty mentioned in His book, and Allah knows best about them. He disliked mentioning them in His book without knowledge."  

عَنْ قَوْلِهِ ﷻ {وَإِنَّ يَوْمًا عِنْدَ رَبِّكَ كَأَلْفِ سَنَةٍ مِمَّا تَعُدُّونَ} [الحج 47] فَقَالَ «مَنْ أَنْتَ؟» فَذَكَرَ لَهُ أَنَّهُ رَجُلٌ مِنْ كَذَا وَكَذَا فَقَالَ ابْنُ عَبَّاسٍ «فَمَا يَوْمٌ كَانَ مِقْدَارُهُ خَمْسِينَ أَلْفَ سَنَةٍ؟» فَقَالَ الرَّجُلُ رَحِمَكَ اللَّهُ إِنَّمَا سَأَلْتُكَ لِتُخْبِرَنَا فَقَالَ ابْنُ عَبَّاسٍ «يَوْمَانِ ذَكَرَهُمَا اللَّهُ ﷻ فِي كِتَابِهِ اللَّهُ أَعْلَمُ بِهِمَا فَكَرِهَ أَنْ يَقُولَ فِي كِتَابِ اللَّهِ بِغَيْرِ عَلْمٍ»
