Sunnah of Rasool Allah -saww would never change due to the fact the Sunnah of Allah ‑azwj does not change, e.g., Allah -azwj Says in the Holy Quran: سُنَّةَ اللَّهِ فِي الَّذِينَ خَلَوْا مِنْ قَبْلُ ۖ وَلَنْ تَجِدَ لِسُنَّةِ اللَّهِ تَبْدِيلًا {62} Being a Sunnah of Allah regarding those who have gone before, and you will never find any alteration in the Sunnah of Allah [33:62] Also, Allah -azwj Says at another place in the Holy Quran: اسْتِكْبَارًا فِي الْأَرْضِ وَمَكْرَ السَّيِّئِ ۚ وَلَا يَحِيقُ الْمَكْرُ السَّيِّئُ إِلَّا بِأَهْلِهِ ۚ فَهَلْ يَنْظُرُونَ إِلَّا سُنَّتَ الْأَوَّلِينَ ۚ فَلَنْ تَجِدَ لِسُنَّتِ اللَّهِ تَبْدِيلًا ۖ وَلَنْ تَجِدَ لِسُنَّتِ اللَّهِ تَحْوِيلًا {43} Behaving arrogantly in the earth and plotting the evil, and the evil plot does not affect any except its perpetrators.

So, are they awaiting except for the ways of the former ones? You will never find a replacement in the Sunnah of Allah, and you will never find an alteration in the Sunnah of Allah [35:43] عَلِيُّ بْنُ مُحَمَّدِ بْنِ بُنْدَارَ عَنْ إِبْرَاهِيمَ بْنِ إِسْحَاقَ عَنْ سَهْلِ بْنِ الْحَارِثِ عَنِ الدِّلْهَاثِ مَوْلَى الرِّضَا ( عليه السلام ) قَالَ سَمِعْتُ الرِّضَا ( عليه السلام ) يَقُولُ لَا يَكُونُ الْمُؤْمِنُ مُؤْمِناً حَتَّى يَكُونَ فِيهِ ثَلَاثُ خِصَالٍ سُنَّةٌ مِنْ رَبِّهِ وَ سُنَّةٌ مِنْ نَبِيِّهِ وَ سُنَّةٌ مِنْ وَلِيِّهِ Ali Bin Muhammad Bin Bundar, from Ibrahim Bin Is’haq, from Sahl Bin Al Haris, from; Al-Dilhat, a slave of Al-Reza -asws who said, ‘I heard Al-Reza ‑asws saying: ‘A Momin cannot happen to be (a Momin ) until there happen to be three characteristics in him – a Sunnah from his Lord -azwj , and a Sunnah from His -azwj Prophet -saww , and a Sunnah from His -azwj Guardian -asws (Imam).

فَأَمَّا السُّنَّةُ مِنْ رَبِّهِ فَكِتْمَانُ سِرِّهِ قَالَ اللَّهُ عَزَّ وَ جَلَّ عالِمُ الْغَيْبِ فَلا يُظْهِرُ عَلى غَيْبِهِ أَحَداً إِلَّا مَنِ ارْتَضى مِنْ رَسُولٍ So, as for the Sunnah from his Lord -azwj , so it is the concealment of His -azwj Secrets. Allah -azwj Mighty and Majestic Says [72:26] The Knower of the unseen! So He does not Reveal His secrets to any, [72:27] Except to him whom He chooses from the Messenger .

وَ أَمَّا السُّنَّةُ مِنْ نَبِيِّهِ فَمُدَارَاةُ النَّاسِ فَإِنَّ اللَّهَ عَزَّ وَ جَلَّ أَمَرَ نَبِيَّهُ ( صلى الله عليه وآله ) بِمُدَارَاةِ النَّاسِ فَقَالَ خُذِ الْعَفْوَ وَ أْمُرْ بِالْعُرْفِ وَ أَمَّا السُّنَّةُ مِنْ وَلِيِّهِ فَالصَّبْرُ فِي الْبَأْسَاءِ وَ الضَّرَّاءِ .
