A Statement concerning the People of Success

Allah says,

قَدْ أَفْلَحَ مَن تَزَكَّى

قَدْ أَفْلَحَ مَن تَزَكَّىٰ (Success is surely achieved by him who purifies himself,..87:14) The word tazakka is derived from zakah, the primitive meaning of which is 'to purify'. The zakah of wealth is so called because it purifies the rest of man's wealth for him. In this context, the word tazakka is used in a general sense, which comprehends the purity of faith and character, and purity of wealth.

وَذَكَرَ اسْمَ رَبِّهِ فَصَلَّىٰ (and pronounces the name of his Lord, then offers prayer....87:15). This covers all categories of prayer, obligatory as well as supererogatory. Some commentators say that it refers especially to Id prayers. This interpretation too can fall under the preceding category.
