The Shaykh’s explanation of the word: (Islam).

The Shaykh : Before we move on to a third hadith, which is roughly the same in meaning as the previous two, I must pause briefly on the word Islam in the first hadith and in the second hadith . To submit means to be guided to Islam. In this hadith, there is a clear indication that if a person combines these two blessings—the spiritual, intangible blessing of being guided to Islam, and the other, material blessing by which he lives for Islam—then happy is that person who was guided to Islam and was provided with a sufficient livelihood, or was content with what Allah (Mighty and Majestic) provided for him.
