النكاح
Abu Hurayrah (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said: “No woman should perform the marriage of another woman, and no woman should perform her own marriage. It is an adulteress who performs her own marriage.”
عن أبي هريرة -رضي الله عنه- قال: قال رسول الله -صلى الله عليه وسلم-: «لا تُزوِّجُ المرأةُ المرأةَ، ولا تُزوج المرأةُ نفسَها، فإنَّ الزَّانية هي التي تُزوجُ نفسَها».
شرح الحديث :
This Hadīth proves that a woman does not have the authority to perform her own marriage, let alone someone else's marriage. Any marriage performed by a woman is void. As for the sentence: "It is an adulteress who performs her own marriage", these are Abu Hurayrah’s words. By this he meant that only adulteresses perform their own marriages, so a chaste woman must not marry without a guardian.
