[Machine] The Prophet ﷺ did not warn against tribulations.
وَمَا كَانَ النَّبِيُّ ﷺ يُحَذِّرُ مِنَ الْفِتَنِ.
The Prophet ﷺ said, "I will be at my Lake-Fount (Kauthar) waiting for whoever will come to me. Then some people will be taken away from me whereupon I will say, 'My followers!' It will be said, 'You do not know they turned Apostates as renegades (deserted their religion).'" (Ibn Abi Mulaika said, "Allah, we seek refuge with You from turning on our heels from the (Islamic) religion and from being put to trial").
عَنِ النَّبِيِّ ﷺ قَالَ أَنَا عَلَى حَوْضِي أَنْتَظِرُ مَنْ يَرِدُ عَلَىَّ فَيُؤْخَذُ بِنَاسٍ مِنْ دُونِي فَأَقُولُ أُمَّتِي فَيَقُولُ لاَ تَدْرِي مَشَوْا عَلَى الْقَهْقَرَى قَالَ ابْنُ أَبِي مُلَيْكَةَ اللَّهُمَّ إِنَّا نَعُوذُ بِكَ أَنْ نَرْجِعَ عَلَى أَعْقَابِنَا أَوْ نُفْتَنَ
The Prophet ﷺ said, "I am your predecessor at the Lake-Fount (Kauthar) and some men amongst you will be brought to me, and when I will try to hand them some water, they will be pulled away from me by force whereupon I will say, 'O Lord, my companions!' Then the Almighty will say, 'You do not know what they did after you left, they introduced new things into the religion after you.'"
قَالَ النَّبِيُّ ﷺ أَنَا فَرَطُكُمْ عَلَى الْحَوْضِ لَيُرْفَعَنَّ إِلَىَّ رِجَالٌ مِنْكُمْ حَتَّى إِذَا أَهْوَيْتُ لأُنَاوِلَهُمُ اخْتُلِجُوا دُونِي فَأَقُولُ أَىْ رَبِّ أَصْحَابِي يَقُولُ لاَ تَدْرِي مَا أَحْدَثُوا بَعْدَكَ
I heard the Prophet ﷺ saying, "I am your predecessor at the Lake-Fount (Kauthar), and whoever will come to it, will drink from it, and whoever will drink from it, will never become thirsty after that. There will come to me some people whom I know and they know me, and then a barrier will be set up between me and them."
سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ أَنَا فَرَطُكُمْ عَلَى الْحَوْضِ مَنْ وَرَدَهُ شَرِبَ مِنْهُ وَمَنْ شَرِبَ مِنْهُ لَمْ يَظْمَأْ بَعْدَهُ أَبَدًا لَيَرِدُ عَلَىَّ أَقْوَامٌ أَعْرِفُهُمْ وَيَعْرِفُونِي ثُمَّ يُحَالُ بَيْنِي وَبَيْنَهُمْ
"I will say those people are from me. It will be said, 'You do not know what changes and new things they did after you.' Then I will say, 'Far removed (from mercy), far removed (from mercy), those who changed (the religion) after me!"
وَأَنَا أَشْهَدُ عَلَى أَبِي سَعِيدٍ الْخُدْرِيِّ لَسَمِعْتُهُ يَزِيدُ فِيهِ قَالَ إِنَّهُمْ مِنِّي فَيُقَالُ إِنَّكَ لاَ تَدْرِي مَا بَدَّلُوا بَعْدَكَ فَأَقُولُ سُحْقًا سُحْقًا لِمَنْ بَدَّلَ بَعْدِي
