SHAFAQNA – Imam Ali (AS) said: Learn the Quran which is the best of words, and understand it (the Quran) well, as it is the spring of the hearts. Seek cure from its light as it is the cure for the chests and illnesses; and recite the Quran well, as it is the best of books . Imam Ali (AS) also said: Any person, who opts for the words of Allah (SWT) as his/her guide, will be guided to the steadiest of ways/paths .
