Ayesha reported,

Abu Bakr رضي الله عنه came riding a horse from his dwelling at al-Sunh. He dismounted and entered the mosque, and he did not speak to the people until he came in to Ayesha. He went straight to the Messenger of Allah ﷺ, who was covered with a striped Yemeni cloak. He uncovered his face, then leaned over him, kissed him, and wept. Then he said, "May my father and mother be sacrificed for you. By Allah, Allah will never combine two deaths upon you. As for the death that was decreed for you, you have died it."

Sahih

عن عائشة

أن أبا بكر رضي الله عنه أقبل على فرس من مسكنه بالسنح، حتى نزل فدخل المسجد فلم يكلم الناس حتى دخل على عائشة، فتيمم رسول الله ﷺ وهو مغشى بثوب حبرة، فكشف عن وجهه، ثم أكب عليه فقبله وبكى، ثم قال: بأبي أنت وأمي، والله لا يجمع الله عليك موتتين، أما الموتة التي كتبت عليك فقد متها.
