Then she went out with us, travelling to Makkah, and it became unclear to us because of the vow: should she fast or break the fast?” Imam عليه السلام said: “She should not fast. Allah سبحانه وتعالى, Mighty and Majestic, has removed His سبحانه وتعالى right from her, and she fasts what she made binding upon herself.” I (narrator) said: “Then what do you see, when she returns to the house, should she make it up?” Imam عليه السلام said: “No.” I (narrator) asked: “Then should she leave that?” Imam عليه السلام said: “No, for I fear that she may see, concerning the matter for which she made the vow, something she dislikes.”
