رسول الله (صلی الله علیه و آله):
إذا التَبَسَتِ الامورُ علَيكُم كَقِطَعِ اللَّيلِ المُظلِمِ فعلَيكُم بالقرآنِ؛ فإنّهُ شافِعٌ مُشَفَّعٌ، وماحِلٌ مُصدَّقٌ، ومَن جَعَلَهُ أمامَهُ قادَهُ إلَى الجَنَّةِ، ومَن جَعَلَهُ خَلفَهُ قادَهُ إلَى النارِ.
The Prophet Muhammad (S):
When matters become obscure for you like the darkness of the night, then turn to the Quran, for it is an intercessor whose intercession is accepted and a complainant whose complaint is acknowledged. Whoever puts it in front of them, it will lead them to Heaven, and whoever puts it behind them, it will drag them to Hell .
