The ruling on concluding the first khutbah with (I say this of mine), and the second with: {Indeed, Allah commands justice}

He also asks and says: I heard some students of knowledge criticizing those who deliver the Friday khutbah and leave out what the preachers have become accustomed to, which is concluding the first Friday khutbah with the preacher’s constant phrase: “I say this of mine and I seek forgiveness from Allah for myself and for you from every sin, so seek forgiveness from Him, for He is the Oft-Forgiving, the Most Merciful,” or concluding the second khutbah with the verse: [al-Nahl: 90]. And whoever leaves this out is criticized, to the point that a student of knowledge said: Leaving out this verse and not concluding the khutbah with it is a religious innovation and contrary to the Sunnah. Please give us a ruling, may Allah reward you with good?
Answer: There is no blame in leaving out what was mentioned. There is no blame if the preacher leaves out: and there is no blame if he leaves out the verse [al-Nahl: 90] in the second khutbah. All of this is without blame. So if someone says it, there is nothing wrong, and if someone leaves it out, there is nothing wrong. Concluding it with the prayer upon the Prophet (peace and blessings be upon him) or with another verse, all of this is without blame.
And the one who says that leaving this out is a religious innovation is mistaken and has no knowledge of the matter. Concluding with this verse is narrated from 'Umar ibn 'Abd al-'Aziz that he used to conclude with this verse. As for , it is narrated from the Prophet (peace and blessings be upon him).
In any case, this is not a mandatory requirement. Concluding the khutbah with (I say this of mine) or with a noble verse, none of it is mandatory. Rather, if the preacher varies the conclusions of the khutbahs with various types of prayer upon the Prophet (peace and blessings be upon him) and other verses or hadiths, all of that is good, so that people do not think that this is something mandatory. Because the preacher has committed to this verse and to saying , some people think that this is something mandatory and that it is a confirmed Sunnah, and that leaving it out is a religious innovation, as the person I mentioned thought. But when the preacher varies it, sometimes he comes with this verse and sometimes he does not, and sometimes he comes with the saying and sometimes he does not, people will know that the matter is broad, and that there is no blame in concluding the khutbahs with this verse or with something else, or with the saying: (I say this of mine) or with something else, so that this matter is clear and evident to people, and people do not fall into error. And success is from Allah. Yes.
The presenter: May Allah bless you and reward you with good.
