Does the reward decrease if one circumambulates while riding, even though he is able to walk?

Question:
He says: You mentioned, may Allah preserve you, yesterday that there is no harm in a person riding in a vehicle during the tawaf, even though he is able to walk. The question, may Allah preserve you, is: Does his reward decrease by doing so, such that he would be like one who prays sitting down while he is able to stand?

Answer:
The Messenger (peace and blessings be upon him) rode while he was strong, may Allah’s peace and blessings be upon him, to make it clear to the people that this is permissible. So it is permissible to ride during the tawaf and during the sa’i, and praise be to Allah. As for the reward, it is with Allah; we do not say that it decreases. We only know that this is with Allah, the Exalted, and it is according to his intention. Yes.
