The Holy Prophet (Peace be upon him) has emphasized importance of Al-Ikhlass (Surah-112), in many ways. I was first fascinated by following Hadiith, to attempt to collect and compile material for research into the content of this Surah:

Prophet Muhammad (Peace be upon him) said:
"By Him (Allah) in Whose hand my soul is, it (Al-Ikhlass) is equal to one-third of the Quran."

(Bukhari, 9-471)

        A curious researcher may himself see whether depth and vastness of the four brief verses of this Supreme Surah are encompassable from its apparently small surface.
