It is narrated from Sayyiduna Uqbah bin Amir (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said to a man: "Are you pleased for me to marry you to so-and-so (a woman)?" He said: "Yes." And he (peace and blessings be upon him) asked the woman: "Are you pleased for me to marry you to so-and-so (a man)?" She said: "Yes." So he (peace and blessings be upon him) married them to each other, but he did not fix a dowry for her, nor did he give her anything (in cash). That man was one of those who had been present at (the treaty of) al-Hudaybiyah, and those of al-Hudaybiyah had a share allotted in Khaybar. When his death drew near, he said: "The Messenger of Allah (peace and blessings be upon him) married me to so-and-so, and I did not fix a dowry for her nor give her anything. I make you witnesses that I have given her my share in Khaybar as her dowry." So the woman took that share and sold it for one hundred thousand (dirhams). The narrator says that the Messenger of Allah (peace and blessings be upon him) said: "The best dowry is the one that is easiest." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
