If someone sees a picture of the grave of the Prophet (blessings and peace of Allah be upon him) and sends greetings of salaam upon him because he has remembered him, there is nothing wrong with that, but this is not the salaam of visitation that is recited at the grave of a deceased person. With regard to his two companions, it is prescribed to pray that Allah be pleased with them and have mercy on them when one remembers them; it is not prescribed to send greetings of salaam to them.

It is permissible to offer Du`a in other than Arabic in the prayer, especially if it is difficult for the person to learn Arabic. He may offer Du`a and ask for whatever he wishes of goodness in this world and the hereafter, and it is not stipulated he should use only words that have been narrated in reports.
