الْفَوْزُ قَرِيبٌ. إِنَّهُ غَيْرُ بَعِيدٍ.
Success is near. Indeed, it is not far away.
The second clause reinforces the first, giving a plausible emphasis reading. Compare this with:
أَحْسَنَ إِلَى أَصْحَابِهِ. أَعَانَ فَقِيرَهُمْ وَعَالَ مَرِيضَهُمْ.
He treated his companions well: he assisted their poor and cared for their sick.
Now the later statements specify what a general act of kindness comprised, making substitution through detail the more salient relation. Semantic closeness alone does not make every second clause an emphatic paraphrase.
