The caution attributed to the Shaykhayn is to perform Hajj in the year it becomes obligatory. Delaying without an excuse is sinful.
Nevertheless, when the outstanding Hajj is performed later, it is still called Ada, not Qada, in this classification.
These statements answer separate questions:
• Should it be delayed without an excuse? No; the stated warning remains.
• What is its later performance called? Ada.
As with the earlier untimed-duty discussion, calling an act Ada does not itself approve an unjustified delay.
