Qasim bin Muhammad both narrated this from Umm Muiminin, and I do not distinguish the wording of one from the other. He said, Ayesha said, "Messenger of Allah, the people are returning having performed two rites, while I am returning having performed only one."He replied, "Wait until you become pure, then go out to Tanim and enter into ihram from there, then meet us." On another occasion he said, "Then meet us at such-and-such a mountain." The narrator said, I think he said such-and-such. "But its reward is in proportion to your effort," or "in proportion to your expenditure," or as the Messenger of Allah ﷺ said.
حدثنا إسماعيل أخبرنا ابن عون عن إبراهيم عن الأسود
وعن القاسم بن محمد يحدثان ذاك عن أم المؤمنين لا أحفظ حديث هذا من حديث هذا قال قالت عائشة يا رسول الله يصدر الناس بنسكين وأصدر بنسك واحد قال انتظري فإذا طهرت فاخرجي إلى التنعيم فأهلي منه ثم القينا وقال مرة ثم وافينا بجبل كذا وكذا قال أظنه قال كذا ولكنها على قدر نصبك أو قدر نفقتك أو كما قال رسول الله ﷺ
