Building

Is one who builds on the foundation of mindfulness of Allah and His pleasure better, or one who builds on the brink of a crumbling cliff, which collapses into the Fire of Hell?

9:109Is he who founded his building upon duty to Allah and His good pleasure better; or he who founded his building on the brink of a crumbling, overhanging precipice so that it toppled with him into the fire of hell? Allah guideth not wrongdoing folk.

The structure they built will remain a source of doubt in their hearts until their hearts are torn apart.

9:110The building which they built will never cease to be a misgiving in their hearts unless their hearts be torn to pieces. Allah is Knower, Wise.
