Arabic (Original)
وَبِإِسْنَادِهِ ذَرُونِي مَا تَرَكْتُكُمْ فَإِنَّمَا هَلَكَ مَنْ كَانَ قَبْلَكُمْ بِسُؤَالِهِمْ وَاخْتِلَافِهِمْ عَلَى أَنْبِيَائِهِمْ فَإِذَا أَمَرْتُكُمْ بِشَيْءٍ فَخُذُوا مِنْهُ مَا اسْتَطَعْتُمْ وَإِذَا نَهَيْتُكُمْ عَنْ شَيْءٍ فَانْتَهُوا.
English Translation
With the same chain of narration: "Leave me as I have left you, for those before you were destroyed only by their excessive questioning and their differing with their prophets. So when I command you to do something, do of it what you are able; and when I forbid you from something, refrain from it."
