One of the black companions of the Prophet (SAWS) was Sa’ad Al-Aswad As-Sulami (RA).
Sa’ad was from the Ansar and suffered discrimination in Al-Madinah.
Due to an inferiority complex, Sa’ad asked the Prophet (SAWS) if he too could enter into Jannah because of his low position among the Muslims. The Prophet (SAWS) replied to him that he was entitled to the same reward as other believers. Sa’ad then inquired that if he was an equal believer then why would none of the Arabs allow him to marry one of their daughters.
The Prophet (SAWS) then told Sa’ad to go to the home of ‘Amr bin Wahb to ask him for his daughter for marriage. When Sa’ad told ibn Wahb that the Prophet (SAWS) sent him to request for his daughter for marriage, ibn Wahb became angry at the proposal. Ibn Wahb also stated to him that didn’t he know that his daughter is known for her beauty! When ibn Wahb’s daughter heard this, she told her father that she could not turn down a proposal that came at the suggestion of the Messenger of Allah (SAWS)!
Sa’ad was later martyred in a battle in which it is narrated that the Prophet (SAWS) wept over him while holding him in his lap.
