Q: Sometimes I am entrusted with certain jobs in Al-Haram-ul-Nabawy (the Prophet’s Mosque in Madinah), where I am to carry out my service in front of the fence around the room of the Prophet's grave. My duty is to prevent visitors from touching and seeking blessings from the Prophet's grave. Upon entering Al-Haram Al-Nabawy, I usually offer Tahiyyat-ul-Masjid (two-unit Prayer to salute the mosque) and then start my work in front of the Prophet's grave. Before starting my job, I invoke blessings upon the Prophet (peace be upon him) and his two Companions (i.e. Abu-Bakr and `Umar, may Allah be pleased with them both). One of my colleagues told me that this deed is not permissible and that the Prophet (peace be upon him) has forbidden (Part No. 1; Page No. 428) making his grave a frequently visited place. Therefore, invoking blessings upon the Prophet and his two Companions daily is impermissible. My question is what is the ruling on me doing this? May Allah grant you success and blessings.
