Nasai

1420. Commentary: The mentioned narration is weak in its chain of transmission; however, an incident of this type is found in Sahih Muslim, in which it is mentioned that during the sermon (khutbah), the sermon was left aside and conversation took place with a questioner. See: [صحیح مسلم ، الجمعة ، حدیث : 876]. In addition, such an incident also occurred on the occasion of a prayer, as is found in Jami‘ at-Tirmidhi: the call to commence the prayer (iqamah) was given, so a person took hold of the hand of the Prophet (sallallahu alayhi wa sallam) and began speaking with him, to the extent that some people began to doze off. See: [جامع الترمذي ، الجمعة ، حدیث : 518]. Furthermore, according to the verifying scholars, the mention of Jumu‘ah (Friday prayer) in the aforementioned narration is anomalous (shadh); that is, this incident was not during Jumu‘ah but rather during the ‘Isha’ prayer. Therefore, if any person or the imam wishes to say something necessary, there is no harm in it, but consideration should be given to the engagement and discomfort of others. And Allah knows best. For further details, see: [ضعیف سنن النسائي ، للألباني ، رقم : 1418 ، و ذخیرة العقبیٰ شرح سنن النسائي : 277/16].

1120. Commentary:
This narration is weak in its chain of transmission. However, an incident of this type, in which during the sermon the sermon was left and conversation with a questioner is mentioned, is found in Sahih Muslim, hadith [876]. In addition, a similar incident occurred on the occasion of a prayer as well. As is found in Jami' al-Tirmidhi, when the iqamah for prayer was pronounced, a person took the hand of the Prophet sallallahu alayhi wa sallam and began speaking with him, to the extent that some people began to doze off. [ترمذي، حديث : 518، ابوداؤد، حديث : 201]
And the ruling is as follows: if the imam or any other person wishes to fulfill a need, there is no harm in it, but the congregation should not be caused any discomfort.
