Is it prohibited to dedicate a specific supplication to a particular need, such as naming a supplication for marriage or a supplication for children?

Supplication (Du'a) is one of the best acts of drawing closer to Allah, and it is worship. Ibn Hajar referred to the hadith: "Whoever among you has the door of supplication opened for him, the doors of mercy have been opened for him." The servant's supplication is answered as long as he does not supplicate for a sin or for the severance of kinship ties. There is no specific supplication for marriage or for a wife to supplicate for her husband, but comprehensive supplications that encompass the good of both this world and the Hereafter include these matters, such as: "Our Lord, grant us in this world [that which is] good and in the Hereafter [that which is] good and protect us from the punishment of the Fire," and "Our Lord, grant us from among our wives and offspring comfort to our eyes and make us leaders for the righteous." It is permissible to supplicate with non-transmitted (non-masnun) supplications, but singling out a specific supplication for a particular need and believing in its guaranteed response without evidence risks falling into the realm of innovation (bid'ah).
