1601. hadíth
وَتَمَسَّكْ بِحَبْلِ الْقُرآنِ وَاسْتَنْصِحْهُ [وَانْتَصِحْهُ]، وَأَحِلَّ حَلَالَهُ، وَحَرِّمْ حَرَامَهُ، وَصَدِّقْ بِمَا سَلَفَ مِنَ الْحَقِّ، وَاعْتَبِرْ بِمَا مَضَى مِنَ الدُّنْيَا لِمَا بَقِيَ مِنْهَا، فَإِنَّ بَعْضَهَا يُشْبِهُ بَعْضاً، وَآخِرَهَا لَاحِقٌ بِأَوَّلِهَا! وَكُلُّهَا حَائِلٌ مُفَارِقٌ.
Adhere to the rope of the Qur’ān and seek instructions from it. Regard its lawful as lawful and its unlawful as unlawful. Testify the right that has been in the past. Take lesson for the present condition of this world from the past (condition), because its one phase resembles the other, and its end is to meet its beginning, and the whole of it is to change and depart.
