Boldness in standing for the truth:
He prayed behind al-Hajjâj bin Yûsuf ath-Thaqafî one time, and he was praying quickly (he would not perform the bowings and prostrations as they should have been performed), so Sa'îd took a handful of stones and hurled them at him. Hajjâj then prayed in a calmer and more careful manner, and this was before al-Hajjâj assumed his position of leadership.
The daughter of the Imâm:
And Sa'îd refused to allow for his daughter to become the first lady of the Islâmic state, and this was when the Khalîfah 'Abdil-Malik wanted to engage her to al-Walîd. Sa'îd starkly refused, and instead married his daughter off to a poor student of knowledge. Sa'îd had a companion by the name of 'Abdullâh bin Wadâ'ah, and one day, he did not come by to see Sa'îd. Sa'îd asked about him and eventually found him, and the man apologized to Sa'îd and informed him that the reason he was away was because his wife was ill and had passed away.
Sa'îd then said to him: "Why did you not inform us of her illness so that we could have visited her, or of her death so that we could attend her funeral prayer?"
Then he said to him: "O 'Abdullâh, get married and do not meet Allâh while you are without a family."
So he said: "May Allâh have Mercy on you, and who will marry me while I am so poor?"
Sa'îd said: "I will marry my daughter to you."
'Abdullâh became quiet out of shyness and Sa'îd asked him: "Why have you become quiet? Is it out of displeasure and refusal of my offer?"
'Abdullâh said: "And where am I from her?"
Sa'îd then said: "Get up and call a group of the Ansâr."
So, he called them to witness the marriage. When they prayed the 'Ishâ,' Sa'îd handed his daughter over to the poor man along with a servant and some money and food, with the groom still unable to believe what was happening to him!
