Shaykh, what is the ruling on making du'a in prayer using words other than those mentioned in the Noble Qur'an?

Du'a in this matter is broad, du'a in this is broad, and for this reason the Prophet ﷺ says, as is reported in the two Sahihs from the narration of Abdullah ibn Mas'ud.

May Allah be pleased with him, he said: Then let him choose from du'a whatever he wishes, and that is at the end of the final tashahhud.

We say: he may choose in du'a, meaning he may supplicate with whatever du'a he wishes for the good of this world and the Hereafter.

And this is evident in the saying of Allah, Verheven en Hoog is Hij: And among them are those who say, Our Lord, grant us good in this world and good in the Hereafter.

This indicates that he may supplicate with whatever he wishes for the good of this world and the Hereafter, and that is with what benefits a person.

For this reason, we say that a person may make du'a for whatever he wishes, and he may choose from the supplications what suits him if he finds words from the Sharia.

There are Sharia-based supplications in the Quran, and also in the sunnah, and mentioning them does not mean they are limited to only those.

It does not mean limitation, but rather that some people may not be able to express their needs well.

Or also, he may not know the permissible words from the prohibited ones and the like, so in that case, he should use what is found in the texts.

Whatever the Prophet ﷺ made du'a with is undoubtedly sunnah, for a person to supplicate, and that is by turning the heart, turning the hearts and eyes, turning his heart to his religion.

Or also, for example, "O Allah, You are Pardoning and love to pardon, so pardon me," or other supplications like, "O Allah, I seek refuge in You from disbelief and poverty." So making du'a with these is sunnah.

As for whether a person is considered to have gone against the sunnah if he does not stick to it, we say: no, rather a person may make du'a as he wishes, except in the situations that have been specified for a certain place or time.

In those cases, he must stick to the prescribed wording, but beyond that, he may make any du'a he wishes, even if he comes up with its wording himself and has not heard it before.

So as long as the wording is permissible and not prohibited, there is no problem with that.
