Al-‘Irbad ibn Sariyah reported: The Messenger of Allah, peace and blessings be upon him, said:

أُوصِيكُمْ بِتَقْوَى اللَّهِ وَالسَّمْعِ وَالطَّاعَةِ وَإِنْ عَبْدٌ حَبَشِيٌّ فَإِنَّهُ مَنْ يَعِشْ مِنْكُمْ يَرَى اخْتِلَافًا كَثِيرًا وَإِيَّاكُمْ وَمُحْدَثَاتِ الْأُمُورِ فَإِنَّهَا ضَلَالَةٌ فَمَنْ أَدْرَكَ ذَلِكَ مِنْكُمْ فَعَلَيْهِ بِسُنَّتِي وَسُنَّةِ الْخُلَفَاءِ الرَّاشِدِينَ الْمَهْدِيِّينَ عَضُّوا عَلَيْهَا بِالنَّوَاجِذِ

You must fear Allah, listen to and obey your leaders, even if an Abyssinian slave is put in charge over you. Whoever lives among you will see many disputes. Beware of newly invented matters, for they are misguidance. Whoever sees them must adhere to my Sunnah and the Sunnah of the upright, guided Caliphs. Bite onto it with your back teeth.

Abu Shurayh al-Khuza’i reported: The Messenger of Allah, peace and blessings be upon him, said:

أَبْشِرُوا وَأَبْشِرُوا أَلَيْسَ تَشْهَدُونَ أَنْ لا إِلَهَ إِلا اللَّهُ وَأَنِّي رَسُولُ اللَّهِ

Rejoice! Do you not witness that there is no God but Allah and I am the messenger of Allah?

They said yes. The Prophet said:

فَإِنَّ هَذَا الْقُرْآنَ سَبَبٌ طَرَفُهُ بِيَدِ اللَّهِ وَطَرَفُهُ بِأَيْدِيكُمْ فَتَمَسَّكُوا بِهِ فَإِنَّكُمْ لَنْ تَضِلُّوا وَلَنْ تَهْلِكُوا بَعْدَهُ أَبَدًا

Verily, this Quran is a rope. One end is in the hand of Allah and the other end is in your hands. Hold fast to it, for you will never be lead astray or ruined ever again.

Jubayr ibn Mut’am reported: The Prophet, peace and blessings be upon him, said:

أَلَيْسَ تَشْهَدُونَ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِيكَ لَهُ وَأَنِّي رَسُولُ اللَّهِ وَأَنَّ الْقُرْآنَ جَاءَ مِنْ عِنْدِ اللَّهِ

Do you not bear witness that there is no God but Allah without any partner, that I am the messenger of Allah, and that the Quran has come from Allah?

We said, “Of course.” The Prophet said:

فَأَبْشِرُوا فَإِنَّ هَذَا الْقُرْآنَ طَرْفُهُ بِيَدِ اللَّهِ وَطَرَفُهُ بِأَيْدِيكُمْ فَتَمَسَّكُوا بِهِ فَإِنَّكُمْ لَنْ تَهْلِكُوا وَلَنْ تَضِلُّوا بَعْدَهُ أَبَدًا

Then rejoice, for one end of this Quran is in the e gives it freely and willingly. You may not wrong each other. Do not turn back to the ways of unbelievers after me, striking the necks of each other.

Moderation in the Sunnah is better than striving in innovation.

إِنِّي أَعْلَمُ أَنَّكَ حَجَرٌ لَا تَضُرُّ وَلَا تَنْفَعُ وَلَوْلَا أَنِّي رَأَيْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُقَبِّلُكَ مَا قَبَّلْتُكَ

Verily, I know you are only a stone with no power to harm or benefit me. Were it not that I saw the Prophet, peace and blessings be upon him, kiss you, I would not have kissed you.

I saw the Messenger of Allah, peace and blessings be upon him, do that, do I did that.

عَنِ ابْنِ عُمَرَ رضي الله عنه أَنَّهُ كَانَ يَأْتِي شَجَرَةً بَيْنَ مَكَّةَ وَالْمَدِينَةِ فَيَقِيلُ تَحْتَهَا وَيُخْبِرُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يَفْعَلُ ذَلِكَ

Ibn Umar, may Allah be pleased with him, would come to a tree between Mecca and Medina, and he would take a nap under it. He told people that the Prophet, peace and blessings be upon him, had done so.
