110 Preface لا يَزالُ بُنيانُهُمُ الَّذي بَنَوا ريبَةً في قُلوبِهِم إِلّا أَن تَقَطَّعَ قُلوبُهُم ۗ وَاللَّهُ عَليمٌ حَكيمٌYusuf AliThe foundation of those who so build is never free from suspicion and shakiness1 in their hearts, until their hearts are cut to pieces. And God is All-Knowing, Wise.The parable is continued further. The heart of man is the seat of his hopes and fears, the foundation of his moral and spiritual life. If that foundation is on an undermined sand cliff already crumbling to pieces, what security or stability can he have? He is being shaken by alarms and suspicions and superstitions, until like the edge of a sand cliff they are cut clean away and fall into a heap of ruin and his spiritual life and all its landmarks are destroyed.
