Sayyiduna Ma'qil bin Yasar (may Allah be pleased with him) said: One day I helped the Messenger of Allah (peace and blessings be upon him) perform ablution, and he (peace and blessings be upon him) said to me: "Would you like to go to Fatimah (may Allah be pleased with her)?" - meaning his daughter. I said: Yes. So he (peace and blessings be upon him) stood up leaning on me and said: "Listen! Someone other than you will carry the burden, but the reward will be yours." It was as if no burden at all remained on me, until we came to Fatimah (may Allah be pleased with her), and he (peace and blessings be upon him) said to her: "How do you find yourself?" She said: By Allah, my grief has become intense, my poverty has grown severe, and my illness has become prolonged. He (peace and blessings be upon him) said: "Are you not pleased that I married you to the earliest of my Ummah to accept Islam, the most knowledgeable of them, and the most forbearing of them?"
