Sahih Muslim 1211r

Abu Bakr ibn Abi Shayba narrated this to us: Ibn Ulayya narrated to us, from Ibn Awn, from Ibrahim, from al-Aswad, from the Mother of the Believers. (Another chain:) From al-Qasim, from the Mother of the Believers, who said: I said: Messenger of Allah, people are returning with two rites, while I am returning with one. He said: Wait. When you are pure, go out to al-Tanim and enter ihram there; then meet us at such-and-such a place—I think he said tomorrow. But that is in proportion to your exertion—or, he said, your expenditure.
