A man says, ‘It is obligatory on me to walk to the house of Allah’ when he is in the state of Ihram for al-Hajj. He may say, ‘It is obligatory on me to offer such and such offering.’ However, he does not owe anything until he says, ‘It is obligatory on me from Allah to walk to His house.’ Or says, ‘It is obligatory from Allah on me to assume the state of Ihram for al-Hajj.’ Or he says, ‘From Allah it is obligatory on me to offer an offering of such and such if I did not do such and such thing.’”
