Abu Saeed Khudri reported,

The Messenger of Allah ﷺ sat on the pulpit and said, "Allah gave one of His servants the choice between receiving as much of the splendor of this world as he wished and what is with Him, and the servant chose what is with Him."Abu Bakr wept and said, "We would ransom you with our fathers and mothers."We were astonished at him, and people said, "Look at this old man. The Messenger of Allah ﷺ is telling him about a servant whom Allah gave the choice between receiving the splendor of this world and what is with Him, and he says, 'We would ransom you with our fathers and mothers.'"But it was the Messenger of Allah ﷺ who had been given the choice, and Abu Bakr was the most knowledgeable among us about it.The Messenger of Allah ﷺ said, "Among the people most generous to me with his companionship and his wealth is Abu Bakr. Were I to take a close friend from my community, I would have taken Abu Bakr, but the bond of Islam is sufficient. Let no door remain open into the mosque except the door of Abu Bakr."

عن أبي سعيد الخدري

أن رسول الله ﷺ جلس على المنبر، فقال: إن عبدا خيره الله بين أن يؤتيه من زهرة الدنيا ما شاء وبين ما عنده، فاختار ما عنده فبكى أبو بكر، وقال: فديناك بآبائنا وأمهاتنا، فعجبنا له، وقال الناس: انظروا إلى هذا الشيخ يخبر رسول الله ﷺ عن عبد خيره الله بين أن يؤتيه من زهرة الدنيا وبين ما عنده، وهو يقول: فديناك بآبائنا وأمهاتنا، فكان رسول الله ﷺ هو المخير، وكان أبو بكر هو أعلمنا به، وقال رسول الله ﷺ: إن من أمن الناس علي في صحبته وماله أبا بكر، ولو كنت متخذا خليلا من أمتي لاتخذت أبا بكر إلا خلة الإسلام، لا يبقين في المسجد خوخة إلا خوخة أبي بكر.
