Muttafaq ‘alayh (Bukhari and Muslim) Sahih al-Bukhari 7288
"Leave me as I leave you. Verily, what destroyed those before you was their asking questions and their disagreement with their prophets. So, if I forbid you from something, avoid it; and if I command you with something, do as much of it as you can…
دَعُونِي مَا تَرَكْتُكُمْ، إِنَّمَا هَلَكَ مَنْ كَانَ قَبْلَكُمْ بِسُؤَالِهِمْ وَاخْتِلاَفِهِمْ عَلَى أَنْبِيَائِهِمْ، فَإِذَا نَهَيْتُكُمْ عَنْ شَىْءٍ فَاجْتَنِبُوهُ، وَإِذَا أَمَرْتُكُمْ بِأَمْرٍ فَأْتُوا مِنْهُ مَا اسْتَطَعْتُمْ "
