The aunt of Hazrat ‘Uthmaan (radhiyallahu ‘anhu), Su‘daa, recited the following poetry when he married the respected daughter of Rasulullah (sallallahu ‘alaihi wasallam), Hazrat Ruqayyah (radhiyallahu ‘anha):

هدى الله عثمان الصيفي بقوله      فأرشده والله يهدي إلى الحق

فتابع بالرأي السديد محمدا      وكان ابن أروى لا يصد عن الحق

وأنكحه المبعوث إحدى بناته      فكان كبدر مازج الشمس في الأفق

فداؤك يا ابن الهاشميين مهجتي      فأنت أمين الله أرسلت في الخلق

Allah has guided His fortunate servant ‘Uthmaan towards the path of guidance. Allah has blessed him with divine guidance and Allah alone guides those whom He wishes towards the truth.

After all, he is the son of Arwaa, and the son of Arwaa treaded on the path of truth and did not move away from it.

And the one sent as the Nabi of Allah (Rasulullah (sallallahu ‘alaihi wasallam)) handed one of his daughters to him in marriage. This union is such that it resembles the sun and the full moon combining on the horizon.

May my life be sacrificed for you, O son of the Banu Haashim (Rasulullah (sallallahu ‘alaihi wasallam))! You are the trustee of Allah over deen and you have been sent for the guidance of the entire creation.

(Isaabah 8/178)
