Answered by Sayyidi Habib Umar bin Hafiz (may Allah protect him and benefit us by him).
With what intention should we recite Surat al-Waq`iah?
We should recite Surat al-Waq`iah with the intention of increasing in certainty and increasing in inward and outward provision. The Surah mentions the states of the hereafter, reflecting upon which is one of the foundations in strengthening one’s certainty. Allah also calls us to strengthen our certainty by looking at the created things around us: Do you see the seed that you sow in the ground? Is it you that cause it to grow or are We the cause? Do you see the water which you drink? Do you bring it down from the clouds or do We?
