Musnad Ahmad 306:2

Yunus narrated to us, he said: Layth—meaning Ibn Sa'd—narrated to us, from Yazid ibn Abdullah ibn Usamah ibn al-Had, from Amr—meaning Ibn Abi Amr—from al-Muttalib, from Umm Salamah, who said: Abu Salamah came to me one day from the Messenger of Allah (may Allah bless him and grant him peace) and said: "I have heard a statement from the Messenger of Allah (may Allah bless him and grant him peace) that has gladdened me. He said: 'No Muslim is afflicted with a calamity and then says, when struck by his calamity, "O Allah, reward me in my calamity and replace it for me with something better than it," except that He does that for him.'" Umm Salamah said: So I memorized that from him. When Abu Salamah died, I said the *istirja* (Inna lillahi wa inna ilayhi raji'un) and said: "O Allah, reward me in my calamity and replace it for me with something better than him." Then I returned to myself and said: "Where would I get someone better than Abu Salamah?" When my waiting period (*iddah*) ended, the Messenger of Allah (may Allah bless him and grant him peace) asked for permission to see me while I was tanning a hide of mine. I washed my hands of the *qarz* (acacia pods used for tanning) and gave him permission. I placed for him a leather cushion stuffed with palm fibers, and he sat upon it and proposed to me. When he finished his speech, I said: "O Messenger of Allah, it is not that I do not desire you, but I am a woman who is intensely jealous, and I fear that you might see something from me for which Allah would punish me. I am a woman who has reached an advanced age, and I have children." He said: "As for what you mentioned regarding jealousy, Allah the Almighty will remove it from you. As for what you mentioned regarding age, I have been afflicted with the same as what has afflicted you. And as for what you mentioned regarding the children, your children are my children." She said: So I submitted to the Messenger of Allah (may Allah bless him and grant him peace), and the Messenger of Allah (may Allah bless him and grant him peace) married her. Umm Salamah said: Allah replaced Abu Salamah for me with someone better than him: the Messenger of Allah (may Allah bless him and grant him peace).
