وَعَلَيْكُمْ بِكِتَابِ اللهِ، فَإِنَّهُ الْحَبْلُ الْمَتِينُ، وَالنُّورُ الْمُبِينُ، وَالشِّفَاءُ النَّافِعُ، وَالرِّيُّ النَّاقِعُ، وَالْعِصْمَةُ لِلْمُتَمَسِّكِ، وَالنَّجَاةُ لَلْمُتَعَلِّقِ، لاَ يَعْوَجُّ فَيُقَامَ، وَلاَ يَزِيغُ فَيُسْتَعْتَبَ، وَلاَ تُخْلِقُهُ كَثْرَةُ الرَّدِّ، وَوُلُوجُ السَّمْعِ، مَنْ قَالَ بِهِ صَدَقَ، وَمَنْ عَمِلَ بِهِ سَبَقَ.
You should adhere to the Book of Allāh because it is the strong rope, a clear light, a benefiting cure, a quenching for thirst, protection for the adherent and deliverance for the attached. It does not curve so as to need straightening and does not deflect so as to be corrected. Frequency of its repetition and its falling on ears does not make it old. Whoever speaks according to it, speaks truth and whoever acts by it is forward (in action).
