The Prophet ﷺ came to the grave of Abdullah bin Ubayy after he had been placed in his pit. He stood over him and ordered that he be brought out, then placed him upon his knees, clothed him in his shirt, and breathed some of his saliva upon him. And Allah the Exalted knows best.
أخبرنا عبد الجبار بن العلاء بن عبد الجبار عن سفيان عن عمرو قال سمعت
أتى النبي ﷺ قبر عبد الله بن أبي وقد وضع في حفرته فوقف عليه فأمر به فأخرج له فوضعه على ركبتيه وألبسه قميصه ونفث عليه من ريقه والله تعالى أعلم
