Destiny / Iqbal poetry English translation

Often men who  don't deserve get might and main,
anon a person's gifts ungraced remain.
Perhaps some rules of logic are concealed,
 Mishaps that lie in wait are not revealed.
there is a fact that all of us can know,
World annals much light on this matter throw.
Fate keeps its eye on the nations do,
 Like two-edged sword can riddle through and through.
