Al-Ahzaab 33:6

The Prophet has a greater claim over the believers than their own selves[3], and his wives are their mothers. And blood relatives are more entitled [to inheritance] than other believers and emigrants according to the Book of Allah unless you do good to your close associates [through bequest][4]. This is written in the Record[5].

[3] He (ﷺ) is more worthy of their obedience and loyalty.
[4] A previous ruling that allowed inheritance between Muslims, especially between the Emigrants and the Helpers, was abrogated. Only relatives can inherit from one another now, whereas non-heirs can have a share through a bequest of a deceased, up to one-third of the estate. See 4:7, 11-13, 32-33, 176, 8:75.
[5] i.e., the Preserved Tablet (al-Lawh al-Mahfūz).

The Prophet is more worthy of the believers than themselves,[1182] and his wives are [in the position of] their mothers. And those of [blood] relationship are more entitled [to inheritance] in the decree of Allāh than the [other] believers and the emigrants, except that you may do to your close associates a kindness [through bequest]. That was in the Book[1183] inscribed.

[1182] He (ﷺ) is more worthy of their obedience and loyalty and is more concerned for them than they are for one another.
[1183] The Preserved Slate (al-Lawḥ al-Maḥfūẓ).

6. The Prophet is closer to the believers than their ownselves,[3] and his wives are their (believers’) mothers (as regards respect and marriage). And blood relations among each other have closer personal ties in the Decree of Allâh (regarding inheritance) than (the brotherhood of) the believers and the Muhâjirûn (emigrants from Makkah), except that you do kindness to those brothers (when the Prophet صلى الله عليه وسلم joined them in brotherhood ties). This has been written in the (Allâh’s Book of Divine) Decrees - (Al-Lauh Al-Mahfûz)."

[3] (V.33:6) Narrated ‘Abdullâh bin Hishâm رضي الله عنه: We were with the Prophet صلى الله عليه وسلم and he was holding the hand of ‘Umar bin Al-Khattâb. ‘Umar said to Him. "O Allâh’s Messenger! You are dearer to me than everything except my ownself." The Prophet صلى الله عليه وسلم said, "No, by Him in Whose Hand my soul is, (you will not have complete Faith) till I am dearer to you than your ownself." Then ‘Umar said to him, now, by Allâh, you are dearer to me than my ownself." The Prophet said, " Now, O ‘Umar, (now you are a believer)." Sahih Al-Bukhari, Vol.8, Hadîth No.682).

The Prophet is closer to the believers than their selves, and his wives are (as) their mothers. And the owners of kinship are closer one to another in the ordinance of Allah than (other) believers and the fugitives (who fled from Mecca), except that ye should do kindness to your friends. This is written in the Book (of nature).
