Surah 42. Ash-Shura, Ayah 19

Latif: so kind, gracious, and understanding, as to bestow gifts finely suited to the needs of the recipients. For the various meanings of Latif, see n. 2844 to xxii. 63. Cf. also xii. 100.

"Servants" here seems to include all men, just and unjust, for Allah provides for them all.

Sustenance, i.e., provision for all needs. "To whom He pleases" is not restrictive, but modal. 'Allah provides for all, but His provision is according to His wise Will and Plan, and not according to people's extravagant demands.' He can provide for all, because He has complete power and can carry out His Will. A further comment will be found in the next verse.
