It is narrated from Hazrat Ibn Abbas (may Allah be pleased with them both) that Allah Almighty has guaranteed for the one who follows the Qur'an that he will not go astray in this world and will not be wretched in the Hereafter. Then he (may Allah be pleased with him) recited: { فَمَنِ اتَّبَعَ ہُدَایَ فَلاَ یَضِلُّ وَلاَ یَشْقَی }.
