Allah (swt) says in the Holy Quran: "Whatever of mercy (i.e., of good), Allah (swt) may grant to mankind, none can withhold it ..." (Fatir 35: 2) Similarly, He opens the doors of sustenance, and success in this world to whomever He wills.
Kha luṅwalo lwa Psalme, Mudzimu u ṱaluswa sa a re na "khathutshelo na tshilidzi"; "ha dzuli é wa u lwa misi yoṱhe, ha dzuli ó sinyuwa maḓuvha manzhi."
