Explanation:

Proposal and Acceptance
In a Muslim Marriage, proposal is referred to as ‘ijab’ and acceptance of the same as ‘qubul’. A proposal should be made by or on behalf of one party and the same should be accepted by the other party. For a valid Muslim marriage, proposal and acceptance should be carried out at the same meeting. If a proposal is made at one meeting and the acceptance of the proposal is done in the second meeting, it is not considered as valid.
