1- This hadith is Hasan Gharib,
2- I asked Muhammad bin Ismail Bukhari, and he said: This hadith is Sahih,
3- Kathir bin Zaid heard from Walid bin Rabah, and Walid bin Rabah heard from Abu Hurairah (may Allah be pleased with him), and they are of acceptable narration,
4- There is also a narration in this chapter from Umm Hani (may Allah be pleased with her).

It is narrated from Umm Hani that she said: "I gave protection to two relatives of my husband, so the Messenger of Allah ( صلی اللہ علیہ وسلم ) said: 'We have also given protection to those whom you have given protection to.'"

Imam Tirmidhi says:
1- This hadith is Hasan Sahih.
2- (This hadith) is narrated through several chains.
3- The people of knowledge act upon this; they have declared it permissible for a woman to grant protection. This is also the opinion of Ahmad and Ishaq bin Rahwayh; they have declared it permissible for a woman and a slave to grant protection.
4- The narrator Abu Murrah, the freed slave of Aqil bin Abi Talib, is also called the freed slave of Umm Hani; his name is Yazid.
