It was narrated that `Asim bin Damrah said:
We asked ‘Ali (رضي الله عنه) about the voluntary prayers of the Prophet (ﷺ) during the day. `Ali said: That was sixteen voluntary rak`ahs that the Messenger of Allah (ﷺ) did during the day, and it is very rare for anyone to persist in doing that. Wakee told us: And my father said: Habeeb bin Abi Thabit said: O Abu Ishaq, I would not like to have gold as much as would fill this mosque in return for this hadeeth of yours.
