Hadees related to Abu Quhafa

Asma binte Abu Bakr Radiyallahu 'anha narrates the story of the acceptance of Islam by Abu Quhafa. When Rasulullah Sallallahu 'alaihi wasallam entered Makkah (on the day it was conquered) and came to Masjidul Haram, Abu Bakr Radiyallahu 'anhu came there holding his father's hand. When Rasulullah Sallallahu 'alaihi wasallam saw them, he said: Why did you not leave this old man at home I would have gone to him myself? Abu Bakr Radiyallahu 'anhu replied: O Rasulallah! It is more of his right that he comes to you instead of your going to him.Rasulullah Sallallahu 'alaihi wasallam made him sit in front of him and stroked his chest and then said: Accept Islam, and he accepted Islam. When Abu Bakr Radiyallahu 'anhu brought his father to Rasulullah Sallallahu 'alaihi wasallam, his hair were as white as the Thaghamah tree; so, Rasulullah Sallallahu 'alaihi wasallam said: Dye his hair. (Musnad
Ahmad, Tabarani, Majma-'uz-Zawaid)

Note: Thaghamah is a tree, which is as white as snow. (Majma Bihar- ul-Anwar).

Hadees Related to Abu Bakr (Radhi Allahu Anhu)

'Aishah Radiyallahu 'anha narrates that: Abu Bakr Radiyallahu 'anhu came out to see Rasulullah Sallallahu 'alaihi wasallam, who was his friend during the period of ignorance. On seeing him he said: O Abul Qasim! You are not seen in the gatherings of your people, and they accuse you of finding faults in their forefathers. Rasulullah Sallallahu 'alaihi wasallam said: Verily, I am ALLAH's Messenger, I invite you to ALLAH. As soon as Rasulullah Sallallahu 'alaihi wasallam completed his words Abu Bakr Radiyallahu 'anhu embraced Islam. When Rasulullah Sallallahu 'alaihi wasallam returned from him, there was no one between the two mountains of Makkah who was happier than him on the acceptance of Islam by Abu Bakr Radiyallahu 'anhu. Then, Abu Bakr went to 'Uthman ibne-'Affan, Talhah ibne- 'Ubaidullah, Zubair ibnil-'Awwam, and Sa'd ibne-Abi Waqqas Radiyallahu anhum. They accepted Islam. Then, the following day, he brought 'Uthman ibne-Ma'azoon, Abu 'Ubaida ibne-Jarrah, 'Abdur Rahman ibne-'Auf, Abu Salama ibne- 'Abdul Asad, and Arqam ibne-abl Arqam and they accepted Islam; may Allah be pleased with them. (Bidayah-wan-Nihayah)

Note: 'Qasim,' is the name of the son of Rasulullah Sallallahu 'alaihi wasallam; and 'Abul Qasim is his Kunniyah, the title usually given to any person with the name of his son or his parent.
