Is it permissible to pause and supplicate at a grave immediately after burial?

Primary text

It is permissible to stand at the grave after the deceased is buried to supplicate for them. This practice is supported by the actions of Imam Ahmad, Al-Ahnaf ibn Qays, and the practice of the Prophet Muhammad (peace be upon him). Evidence confirms that when the Prophet buried a person, he stood over the grave and commanded: 'Ask forgiveness for your brother and ask for him steadfastness, for he is now being questioned.' This hadith is narrated by Abu Dawud.
