عَنْ عُمَرَ بْنِ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ قَالَ: سَأَلَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ رَجُلٌ مِنْ جُهَيْنَةَ أَوْ مُزَيْنَةَ فَقَالَ: يَا رَسُولَ اللَّهِ! فِيمَا نَعْمَلُ، أَفِي شَيْءٍ قَدْ خَلَا أَوْ مَضَى أَوْ فِي شَيْءٍ يُسْتَأْنَفُ الْآنَ؟ قَالَ: ((فِي شَيْءٍ قَدْ خَلَا أَوْ مَضَى)) فَقَالَ رَجُلٌ أَوْ بَعْضُ الْقَوْمِ: يَا رَسُولَ اللَّهِ! فِيمَا نَعْمَلُ؟ قَالَ: ((أَهْلُ الْجَنَّةِ مُيَسَّرُونَ لِعَمَلِ أَهْلِ الْجَنَّةِ وَأَهْلُ النَّارِ مُيَسَّرُونَ لِعَمَلِ أَهْلِ النَّارِ))
It is narrated from Sayyiduna Umar bin Khattab (may Allah be pleased with him) that a man from the tribe of Juhaina or Muzaina asked the Noble Prophet (peace and blessings be upon him): "O Messenger of Allah! According to what are we acting? Is it according to that (decree) which has already passed, or according to something new?" The Prophet (peace and blessings be upon him) replied: "According to that which has already passed." That man, or someone else, said: "O Messenger of Allah! Then what is the reality of action?" The Prophet (peace and blessings be upon him) said: "The actions of the people of Paradise are made easy for those destined for Paradise, and the actions of the people of Hell are made easy for those destined for Hell."
