Conditions

Volume 3, Book 50, Number 874:
Narrated Marwan and al-Miswar bin Makhrama:
(from the companions of Allah's Apostle) When Suhail bin Amr agreed to the Treaty (of Hudaibiya), one of the things he stipulated then, was that the Prophet should return to them (i.e. the pagans) anyone coming to him from their side, even if he was a Muslim; and would not interfere between them and that person. The Muslims did not like this condition and got disgusted with it. Suhail did not agree except with that condition. So, the Prophet agreed to that condition and returned Abu Jandal to his father Suhail bin 'Amr. Thenceforward the Prophet returned everyone in that period (of truce) even if he was a Muslim. During that period some believing women emigrants including Um Kalthum bint Uqba bin Abu Muait who came to Allah's Apostle and she was a young lady then. Her relative came to the Prophet and asked him to return her, but the Prophet did not return her to them for Allah had revealed the following Verse regarding women:
"O you who believe! When the believing women come to you as emigrants. Examine them, Allah knows best as to their belief, then if you know them for true believers, Send them not back to the unbelievers, (for) they are not lawful (wives) for the disbelievers, Nor are the unbelievers lawful (husbands) for them (60.10)
Narrated 'Urwa: Aisha told me, "Allah's Apostle used to examine them according to this Verse: "O you who believe! When the believing women come to you, as emigrants test them . . . for Allah is Oft-Forgiving, Most Merciful." (60.10-12) Aisha said, "When any of them agreed to that condition Allah's Apostle would say to her, 'I have accepted your pledge of allegiance.' He would only say that, but, by Allah he never touched the hand of any women (i.e. never shook hands with them) while taking the pledge of allegiance and he never took their pledge of allegiance except by his words (only)."

Volume 3, Book 50, Number 878:
Narrated Urwa:
Aisha told me that Buraira came to seek her help in writing for emancipation and at that time she had not paid any part of her price. 'Aisha said to her, "Go to your masters and if they agree that I will pay your price (and free you) on condition that your Wala' will be for me, I will pay the money." Buraira told her masters about that, but they refused, and said, "If 'Aisha wants to do a favor she could, but your Wala will be for us." Aisha informed Allah's Apostle of that and he said to her, "Buy and manumit Buraira as the Wala' will go to the manumitted."
Volume 3, Book 50, Number 879:
Narrated Jabir:
While I was riding a (slow) and tired camel, the Prophet passed by and beat it and prayed for Allah's Blessings for it. The camel became so fast as it had never been before. The Prophet then said, "Sell it to me for one Uqiyya (of gold)." I said, "No." He again said, "Sell it to me for one Uqiyya (of gold)." I sold it and stipulated that I should ride it to my house. When we reached (Medina) I took that camel to the Prophet and he gave me its price. I returned home but he sent for me (and when I went to him) he said, "I will not take your camel. Take your camel as a gift for you." (Various narrations are mentioned here with slight variations in expressions relating the condition that Jabir had the right to ride the sold camel up to Medina).
