' I heard Salim bin 'Abdullah narrating a Hadith from his father who said: "'Umar said : "O Messenger of Allah! Do you see that what we do is a new matter- or a matter initiated – or it is a matter already concluded?” He ﷺ said: “ O Ibn Al-Khattab! It is a matter already concluded. For everyone is suited (for that for which he is created). As for one who is among the people of happiness, then he works for happiness, and as for the one who is among the people of misery, then he works for his misery.” (Hasan)  

عُمَرُ يَا رَسُولَ اللَّهِ أَرَأَيْتَ مَا نَعْمَلُ فِيهِ أَمْرٌ مُبْتَدَعٌ أَوْ مُبْتَدَأٌ أَوْ فِيمَا قَدْ فُرِغَ مِنْهُ فَقَالَ فِيمَا قَدْ فُرِغَ مِنْهُ يَا ابْنَ الْخَطَّابِ وَكُلٌّ مُيَسَّرٌ أَمَّا مَنْ كَانَ مِنْ أَهْلِ السَّعَادَةِ فَإِنَّهُ يَعْمَلُ لِلسَّعَادَةِ وَأَمَّا مَنْ كَانَ مِنْ أَهْلِ الشَّقَاءِ فَإِنَّهُ يَعْمَلُ لِلشَّقَاءِ  

"We were with the Messenger of Allah ﷺ and he was scraping the ground, when he raised his head to the heavens, then said: 'There is not one of you but (his place) is known' – Waki said: 'His place has been decreed (be it) in the Fire, and (or) his place in Paradise.' They said: 'Shall we not rely upon this O Messenger of Allah?' He said: 'No. Work, for everyone is facilitated for what he was created.'”(Sahih)  

بَيْنَمَا نَحْنُ مَعَ رَسُولِ اللَّهِ ﷺ وَهُوَ يَنْكُتُ فِي الأَرْضِ إِذْ رَفَعَ رَأْسَهُ إِلَى السَّمَاءِ ثُمَّ قَالَ مَا مِنْكُمْ مِنْ أَحَدٍ إِلاَّ قَدْ عُلِمَ وَقَالَ وَكِيعٌ إِلاَّ قَدْ كُتِبَ مَقْعَدُهُ مِنَ النَّارِ وَمَقْعَدُهُ مِنَ الْجَنَّةِ قَالُوا أَفَلاَ نَتَّكِلُ يَا رَسُولَ اللَّهِ قَالَ لاَ اعْمَلُوا فَكُلٌّ مُيَسَّرٌ لِمَا خُلِقَ لَهُ
