Must the first wife be compensated for the days her husband spends with the second wife during Hajj, even though the first wife had previously performed Hajj with him?

The husband is obligated to compensate his first wife for the same duration he will spend with his second wife during the Hajj, because his travel with the second wife was for her need and benefit. This does not waive the first wife's right to equitable division [of time], and his previous Hajj with the first wife does not affect the command to compensate her.
