"One day after the morning Salat, the Messenger of Allah ﷺ exhorted us to the extent that the eyes wept and the hearts shuddered with fear. A man said: 'Indeed this is a farewell exhortation. [So what] do you order us O Messenger of Allah?' He said: 'I order you to have Taqwa of Allah, and to listen and obey, even in the case of an Ethiopian slave. Indeed, whomever among you lives, he will see much difference. Beware of the newly invented matters, for indeed they are astray. Whoever among you sees that, then he must stick to my Sunnah and the Sunnah of the rightly guided Khulafa', cling to it with the molars.'"  

وَعَظَنَا رَسُولُ اللَّهِ ﷺ يَوْمًا بَعْدَ صَلاَةِ الْغَدَاةِ مَوْعِظَةً بَلِيغَةً ذَرَفَتْ مِنْهَا الْعُيُونُ وَوَجِلَتْ مِنْهَا الْقُلُوبُ فَقَالَ رَجُلٌ إِنَّ هَذِهِ مَوْعِظَةُ مُوَدِّعٍ فَمَاذَا تَعْهَدُ إِلَيْنَا يَا رَسُولَ اللَّهِ قَالَ أُوصِيكُمْ بِتَقْوَى اللَّهِ وَالسَّمْعِ وَالطَّاعَةِ وَإِنْ عَبْدٌ حَبَشِيٌّ فَإِنَّهُ مَنْ يَعِشْ مِنْكُمْ يَرَى اخْتِلاَفًا كَثِيرًا وَإِيَّاكُمْ وَمُحْدَثَاتِ الأُمُورِ فَإِنَّهَا ضَلاَلَةٌ فَمَنْ أَدْرَكَ ذَلِكَ مِنْكُمْ فَعَلَيْهِ بِسُنَّتِي وَسُنَّةِ الْخُلَفَاءِ الرَّاشِدِينَ الْمَهْدِيِّينَ عَضُّوا عَلَيْهَا بِالنَّوَاجِذِ  

narrated from his father, from his grandfather that the Prophet ﷺ said to Bilal bin Al-Harith: "Know." He said: "I am ready to know O Messenger of Allah!" He ﷺ said: "That indeed whoever revives a Sunnah from my Sunnah which has died after me, then for him is a reward similar to whoever acts upon it without diminishing anything from their rewards. And whoever introduces an erroneous innovation which Allah is not pleased with, nor His Messenger, then he shall receive sins similar to whoever acts upon it, without that diminishing anything from the sins of the people.'"  

أَنَّ النَّبِيَّ ﷺ قَالَ لِبِلاَلِ بْنِ الْحَارِثِ اعْلَمْ قَالَ مَا أَعْلَمُ يَا رَسُولَ اللَّهِ قَالَ اعْلَمْ يَا بِلاَلُ قَالَ مَا أَعْلَمُ يَا رَسُولَ اللَّهِ قَالَ أَنَّهُ مَنْ أَحْيَا سُنَّةً مِنْ سُنَّتِي قَدْ أُمِيتَتْ بَعْدِي فَإِنَّ لَهُ مِنَ الأَجْرِ مِثْلَ مَنْ عَمِلَ بِهَا مِنْ غَيْرِ أَنْ يَنْقُصَ مِنْ أُجُورِهِمْ شَيْئًا وَمَنِ ابْتَدَعَ بِدْعَةَ ضَلاَلَةٍ لاَ يَرْضَاهَا اللَّهُ وَرَسُولُهُ كَانَ عَلَيْهِ مِثْلُ آثَامِ مَنْ عَمِلَ بِهَا لاَ يَنْقُصُ ذَلِكَ مِنْ أَوْزَارِ النَّاسِ شَيْئًا  

"The Messenger of Allah ﷺ said to me: 'O my son! If you are capable of (waking up in) the morning and (ending) the evening, while there is nothing of deception in your heart for anything, then do so.' Then he said to me: 'O my son! That is from my Sunnah. Whoever revives my Sunnah then he has loved me. And whoever loved me, he shall be with me in Paradise.'"  

لِي رَسُولُ اللَّهِ ﷺ يَا بُنَىَّ إِنْ قَدَرْتَ أَنْ تُصْبِحَ وَتُمْسِيَ لَيْسَ فِي قَلْبِكَ غِشٌّ لأَحَدٍ فَافْعَلْ ثُمَّ قَالَ لِي يَا بُنَىَّ وَذَلِكَ مِنْ سُنَّتِي وَمَنْ أَحْيَا سُنَّتِي فَقَدْ أَحَبَّنِي وَمَنْ أَحَبَّنِي كَانَ مَعِي فِي الْجَنَّةِ وَفِي الْحَدِيثِ قِصَّةٌ طَوِيلَةٌ
