Read all Ahadith in chapters on wala' and gifts by jami al tirmizi

Aishah narrated that she wanted to buy Barrirah but (her owners) stipulated that they should have her Wala', so the Prophet (s.a.w) said: The Wala' is for the one who gives the price, or for the one who grants the favor. [Abu 'Eisa said:] There are narrations on this topic from Ibn 'Umar and Abu Hurairah. This Hadith is Hasan Sahih, and this is acted upon according to the people of knowledge.

Abdullah bin 'Umar narrated that : the Messenger of Allah (ﷺ) prohibited selling the Wala' and [from] conferring it. [Abu 'Eisa said:] This Hadith is Hasan Sahih. We do not know of it except as a narration of 'Abdullah bin Dinar from Ibn 'Umar from the Prophet (ﷺ). Shu'bah, Sufyan Ath-Thawri, and Malik bin Anas (also) reported it from 'Abdullah bin Dinar. It has been related that Shu'bah said: I so wished that 'Abdullah bin Dinar would permit me when he narrated this Hadith that I stand-up, so that I kiss his head. And Yahya bin Sulaim reported this Hadith from 'Ubaidullah bin 'Umar from Nafi', from Ibn 'Umar from the Prophet (ﷺ). But this is mistaken, Yahya bin Sulaim erred in it, what is correct is: From 'Ubaidullah bin 'Umar, from 'Abdullah bin Dinar, from Ibn 'Umar from the Prophet (ﷺ). This is how it is reported by more than one narrator from 'Ubaidullah bin 'Umar. [Abu 'Eisa said:] And 'Abdullah bin Dinar is alone with this Hadith.

Ibrahim At-Taimi narrated from his father: 'Ali delivered a Khutbah for us in which he said: 'Whoever claims that we have some book to read other than Allah's Book and this paper, which include camel's ages and things related to (relatiation for) wounds, then he has lied. And he said in it: Al-Madinah is sacred, what is between 'Air to Thawr, so whoever introduces in it any innovation or shelters an innovator then upon him is the curse of Allah, the angels, and all people. On the Day of Judgment, Allah will not accept his compulsory nor optional good deeds. And whoever claims someone else to be his father, or claims Wala' for someone other than his Mawali, then upon him is the curse of Allah, the angels, and the people; his compulsory and optional good deeds shall not be accepted. The covenants of the Muslims are one, it covers the rest of them. [Abu 'Eisa said:] This Hadith is Hasan Sahih. Some of them reported it similarly from Al-A'mash, from Ibrahim At-Taimi, from Al-Harith bin Suwaid from 'Ali. [Abu 'Eisa said:] It has been reported through more than one route from 'Ali [from the Prophet (ﷺ)].

Abu Hurairah narrated : that a man from [Banu] Fazarah came to the Prophet (ﷺ) and said: 'O Messenger of Allah (ﷺ)! My wife gave birth to black boy. So the Prophet (s.a.w) said: [Do you have any camels?] He said: 'Yes. He said: Then what are their colors? He said: Red. He said: Is there a gray one among them? He said: Yes, there is a grey one among them. He said: From where does that come? He said: Perhaps it is hereditary. He said: Then in the same way, perhaps it is his heredity. [Abu 'Eisa said:] This Hadith is Hasan Sahih.

Aishah narrated that the Prophet (ﷺ) visited her in a very happy mood, his face beaming with joy and said: Don't you see that the Mujazziz looked just now at Zaid bin Harithah and Usamah bin Zaid, and said: 'These feet belong to each other.' [Abu 'Eisa said:] This Hadith is Hasan Sahih. Sufyan bin 'Uyainah reported this Hadith from Az-Zuhri, from 'Urwah, from 'Aishah and he added in it: Dont you see that the Mujazziz passed by Zaid bin Harithah and Usamah bin Zaid while their heads were covered, and their feet were exposed, and he said: 'These feet belong to each other.' This is how Sa'eed bin Abdur-Rahman - and more than one narrator - narrated this Hadith from Sufyan bin 'Uyanah, from Az-Zuhri, from 'Urwah, from A'ishah. And this Hadith is Hasan Sahih. Some of the people of knowledge used this Hadith to support the case of Qa'if.

Abu Hurairah narrated that the Prophet (s.a.w) said: Give gifts, for indeed the gift removes bad feelings from the chest. And let the neighbor not look down upon (the gift of) her neighbor, even if it be the lower shanks of sheep. [Abu 'Eisa said:] This Hadith is Gharib from this route. Abu Ma'shar's name is Najih, the freed slave of Banu Hisham. Some of the people of knowledge criticized him due to his poor memory.

Ibn 'Umar narrated that the Messenger of Allah (S.A.W)said: The parable of the one who gives a gift, and then takes it back, is that of a dog who eats until he is full, and vomits, then he returns to [take back] his vomit. [Abu 'Eisa said:] There are narrations on this topic from Ibn 'Abbas and 'Abdullah bin 'Amr.

Ibn 'Umar and Ibn 'Abbas narrated the Marfu Hadith: It is not lawful for a man to give a gift and then take it back, except in the case of the father with what he gave to his son. And the parable of the one who gives a gift, and then takes it back, is that of a dog who eats until he is full, and vomits, then he returns to his vomit. [Abu 'Eisa said:] This Hadith is Hasan Sahih. Ash-Shafi'i said: It is not lawful for one who confers something to take it back, except in the case of the father. He may take back what he gave his son and he used this Hadith as proof.
