The cited words command tawaf without themselves stating the condition of ritual ablution. Hanafi reasoning takes the Quranic obligation of tawaf as the foundational command, then separately assesses the legal rank of purification evidence.
If every additional condition were incorporated into the Quranic essence of tawaf, the ruling for a tawaf performed without ablution would be different. This illustrates the practical consequences of absolute versus qualified wording.
