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.

-The Du`a for a new month reported from the Companions is: “O Allah, make this month for us a month of security, faith, safety and Islam, of protection from the Shaytan, and of attaining the good pleasure of the Most Gracious. ” -Though one narration is inauthentic, a corroborating Hadith with a sound chain supports it. Scholars agree that it is good for Muslims to recite this Du`a when a new month begins.
