Ayesha reported,

The Messenger of Allah ﷺ ordered that the slain be cast into the well, so they were thrown into it, except for Umaya bin Khalaf, whose body had swollen inside his armor until it filled it. When they tried to move him, his flesh began to fall apart, so they left him where he was and covered him with enough earth and stones to conceal him… The hadith continues at length and will appear in full in its proper place.

عن عائشة قالت

أمر رسول الله ﷺ بالقتلى أن يطرحوا في القليب، فطرحوا فيه، إلا ما كان من أمية بن خلف، فإنه انتفخ في درعه فملأها، فذهبوا ليحركوه فتزايل (لحمه) فأقروه وألقوا عليه ما غيبه من التراب والحجارة…، الحديث بطوله وسيأتي في موضعه كاملا.
