Mukhtasar Muslim (Abridged) 802 — Permission required for marrying

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: A widow should not be married until her permission is sought, nor should a virgin be married until her permission is sought. The people asked, "O Messenger of Allah! How is the permission of a virgin taken?" He (peace and blessings be upon him) said: Her permission is her silence.
