Jami` at-Tirmidhi, Volume 4, Book 30, Hadith 2135 (DarusSalam) ⓘ

'Asim bin 'Ubaidullah said: ' 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 (s.a.w) 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)

حَدَّثَنَا بُنْدَارٌ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، حَدَّثَنَا شُعْبَةُ، عَنْ عَاصِمِ بْنِ عُبَيْدِ اللَّهِ، قَالَ سَمِعْتُ سَالِمَ بْنَ عَبْدِ اللَّهِ، يُحَدِّثُ عَنْ أَبِيهِ، قَالَ قَالَ 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 ‏" ‏ ‏.‏ قَالَ أَبُو عِيسَى وَفِي الْبَابِ عَنْ عَلِيٍّ وَحُذَيْفَةَ بْنِ أَسِيدٍ وَأَنَسٍ وَعِمْرَانَ بْنِ حُصَيْنٍ ‏.‏ وَهَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ ‏.‏
