عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ عُمَرُ: يَا رَسُولَ اللَّهِ! أَرَأَيْتَ مَا نَعْمَلُ فِيهِ، أَفِي أَمْرٍ قَدْ فُرِغَ مِنْهُ أَمْ مُبْتَدَأٍ أَوْ مُبْتَدَعٍ؟ قَالَ: ((فِيمَا قَدْ فُرِغَ مِنْهُ، فَاعْمَلْ يَا ابْنَ الْخَطَّابِ! فَإِنَّ كُلًّا مُيَسَّرٌ، أَمَّا مَنْ كَانَ مِنْ أَهْلِ السَّعَادَةِ فَإِنَّهُ يَعْمَلُ لِلسَّعَادَةِ، وَأَمَّا مَنْ كَانَ مِنْ أَهْلِ الشَّقَاءِ فَإِنَّهُ يَعْمَلُ لِلشَّقَاءِ))
It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that Sayyiduna Umar (may Allah be pleased with him) said: "O Messenger of Allah! What is your opinion about the deeds we are doing, are they according to that (destiny) which has already been decided, or are they just beginning now and being created?" The Prophet (peace and blessings be upon him) said: "They are according to that (destiny) which has already been decided, O Ibn Khattab! Act, for everyone has been made easy (towards what he was created for), so whoever is among the fortunate, he acts for fortune, and whoever is among the wretched, he acts for wretchedness."
