Is it permissible to supplicate to Allah using names such as "the Benefiter, the Harmer, the Granter of Success," or must one be restricted to His established Beautiful Names?

It has not been established that (al-Dharr, al-Nafi') are among the Most Beautiful Names of Allah, and the hadith in which they were mentioned is weak. However, it is permissible to supplicate with them by way of informing, not by way of naming, for success, harm, and benefit are only from Allah, bearing in mind that al-Dharr should not be mentioned separately from al-Nafi'.
