The questioner : From the questions of this questioner, O honorable Shaykh, he says: Ibn al-Qayyim mentioned in the book "al-Da' wa al-Dawa'" "al-Jawab al-Kafi" in the chapter on the times of supplication that among the times is after the prayers, meaning after the end of the prayer, but he did not say before the taslim, and he also did not mention a verse or a hadith or a reference. So is individual supplication with raising the hands after the prayer permissible or not, and what is the evidence? May you be rewarded.

The Shaykh : Yes. I say that the Quranic and Prophetic texts explain one another. So when the word "after the prayer" (dabr al-salah) comes, we look: if what is qualified by "after the prayer" is supplication, then the meaning of "after the prayer" is its end, before the taslim. And if what is qualified by "after the prayer" is dhikr, then the meaning is what is after the taslim. The evidence for this: as for the first, because the Prophet (peace and blessings be upon him), when he mentioned the tashahhud, said This indicates that what is after the tashahhud and before the taslim is a place for supplication, so let a person take advantage of it by supplicating to Allah the Exalted with whatever he loves. So whatever comes of supplication qualified by "after the prayer" we understand it to be what is in the end of the prayer.
If someone asks: Is "dabr" of a thing part of the thing, or is "dabr" of a thing what comes after it? We say: according to the context, it can be what comes after it, and it can be what comes before it. So "dabr al-salah" is interpreted according to what the evidence requires. So if supplication is attached to "dabr al-salah," the meaning is its end, before the taslim. Among this is what the Prophet (peace and blessings be upon him) commanded Mu'adh to do, where he said So this supplication is before the taslim. But if what is qualified by "dabr al-salah" is dhikr, then it is after the prayer, by the saying of Allah Blessed and Exalted is He So this is the rule in this issue. The saying of the Messenger (peace and blessings be upon him) meaning obligatory The meaning of "dabr" here is what is after the taslim, because that is the place for dhikr. Yes.

The questioner : May Allah reward you and bless you, O honorable Shaykh.
