The Du‘a’ can be recited in a plural, dual, or feminine form, according to who the Salah (Prayer) is being performed for. If the gender of the person is not known, it is permissible to use a masculine form to refer to the Mayt (masculine word in Arabic referring to the dead) or a feminine form to refer to the Janazah (feminine word in Arabic referring the funeral). (Part No. 8; Page No. 386) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
