Reciting Talqin after death

Q 1: Is it permissible to stand at the grave after burial to supplicate to Allah and seek His forgiveness for the dead person?

A: Yes, it is not only permissible but also Mustahab (desirable) to do so. It has been reported by (Part No. 9; Page No. 94)  Abu Dawud, and Al-Hakim who authenticated it on the authority of `Uthman (may Allah be pleased with him): Whenever the Messenger of Allah (peace be upon him) finished burying the dead, he used to stay at his grave and say: 'Seek forgiveness for your brother and beg steadfastness for him, for he will be questioned now.' .
