Narrated Abu Huraira:

The Prophet (ﷺ) said, "I am closer to the believers than their selves in this world and in the Hereafter, and if you like, you can read Allah's Statement: "The Prophet (ﷺ) is closer to the believers than their own selves." (33.6) So, if a true believer dies and leaves behind some property, it will be for his inheritors (from the father's side), and if he leaves behind some debt to be paid or needy offspring, then they should come to me as I am the guardian of the deceased."

Narrated `Aisha:

(the wife of the Prophet) Abu Hudhaifa, one of those who fought the battle of Badr, with Allah's Apostle adopted Salim as his son and married his niece Hind bint Al-Wahd bin `Utba to him' and Salim was a freed slave of an Ansari woman. Allah's Messenger (ﷺ) also adopted Zaid as his son. In the Prelslamic period of ignorance the custom was that, if one adopted a son, the people would call him by the name of the adopted-father whom he would inherit as well, till Allah revealed: "Call them (adopted sons) By (the names of) their fathers." (33.5)

Narrated `Aisha:

As regards the following Qur'anic Verse:-- "When they came on you from above and from below you (from east and west of the valley) and when the eyes grew wild and the hearts reached up to the throats....." (33.10) That happened on the day of Al-Khandaq (i.e. Trench).

Narrated Abu Huraira:

The Prophet (ﷺ) said, "There is no believer but I, of all the people, I am the closest to him both in this world and in the Hereafter. Recite if you wish: 'The Prophet (ﷺ) is closer to the believers than their own selves.' (33.6) so if a believer (dies) leaves some property then his relatives will inherit that property; but if he is in debt or he leaves poor children, let those (creditors and children) come to me (that I may pay the debt and provide for the children), for them I am his sponsor (surely).
