Marriage in Ihraam (Hadith No. 1558)

Bismillah.

Volume 3, Book 29, Number 63:

Narrated Ibn ‘Abbas (radiallaahu `anhu):

The Prophet (sallallaahu `alayhi wasallam) married Maimuna (radiallaahu `anhaa) while he was in the state of Ihram, (only the ceremonies of marriage were held).

This opinion, as discussed by scholars, was that of Ibn `Abbas (radiallaahu `anhu) only, who was most likely mistaken in this. Maimuna (radiallaahu `anhaa) herself says she did not get married in the state of Ihraam. See Abu Dawud: 1843 and Muslim: 1411.

Also, `Uthman (b. ‘Affan) reported it directly from Allah’s Apostle (may peace be upon him) that he said:

A Muhrim should neither marry (in that state) nor make the proposal of marriage.
[Sunan an-Nasa’i 2844, Sahih Muslim 1409]

However, there’s an exception. Someone who has exited the first stage of Ihraam may get married [contract only], however, intercourse will only be permissible once second stage of Ihraam has been exited completely as well. [IslamQA]
