The most blessed of women is the one with the easiest dowry

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that the Prophet (peace and blessings be upon him) said: "The most blessed of women is the one whose dowry is the easiest (and least)."
This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Sahl bin Sa'd (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) married a man to a woman in return for an iron ring whose stone was of silver.
This hadith has a sahih (authentic) chain, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyidah Umm Salamah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever is struck by a calamity should say: 'Inna lillahi wa inna ilayhi raji'un, Allahumma 'indaka ahtasibu musibati, fa'jurni fiha wa abdilni khayran minha' (We belong to Allah and to Him we return; O Allah, with You I seek the reward for my calamity, so reward me for it and give me something better than it in exchange)." Umm Salamah (may Allah be pleased with her) relates: When Abu Salamah died, I said these words, but whenever I reached the part "give me something better than it in exchange," I would say to myself: "Who could be better than Abu Salamah?!" Yet I still recited it. When her waiting period ('iddah) was complete, the Messenger of Allah (peace and blessings be upon him) sent Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) to her with a proposal of marriage. She said to her son: "O Umar, get up and marry me to the Messenger of Allah (peace and blessings be upon him)," and so he performed the marriage. Then the Messenger of Allah (peace and blessings be upon him) would come to her in order to consummate the marriage, but whenever she saw him (peace and blessings be upon him), she would pick up her daughter Zaynab and seat her in her lap, and the Messenger of Allah (peace and blessings be upon him) would go back (out of modesty). Sayyiduna Ammar bin Yasir (may Allah be pleased with him), who was her foster brother, came to know of this, so he came and said: "Where is this wretched little girl who has been standing in the way of the Messenger of Allah (peace and blessings be upon him)?" Then he picked her up and took her away. After that the Messenger of Allah (peace and blessings be upon him) came and entered the house; he (peace and blessings be upon him) cast his eyes around the corners of the house and asked: "What has become of Zunab (little Zaynab)?" She said that Ammar had come and taken her away. So the Messenger of Allah (peace and blessings be upon him) consummated the marriage with her and said: "I will not give you any less in the dowry than what I gave so-and-so (another wife), namely: two hand-mills, two water jars, and a leather cushion stuffed with palm fibre." And he (peace and blessings be upon him) also said: "If I stay with you for seven days, then I will have to stay seven days each with all my wives."
This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.
