The wording is al-Bukhārī’s. Al-Mukhalliṣ said, “remembering Allah,” in place of “engaging in no idle talk.” Al-Mundhirī (2/121), followed by al-Haythamī (3/245), said: “Its narrators are trustworthy!” That is what they both said, but in my view it has two defects.
The first is its being mursal, for this al-Munkadir—namely, al-Munkadir ibn ʿAbd Allāh ibn al-Hudayr al-Tamīmī—although al-Ṭabarānī and others listed him among the Companions, this has not been established. Ibn Abī Ḥātim said (4/1/406): “He narrated from the Prophet—may Allah bless him and grant him peace—but his Companionship is not established; and he narrated from ʿUmar ibn al-Khaṭṭāb.” Ibn ʿAbd al-Barr said in al-Istīʿāb (4/1486): “His hadith is considered mursal by them, and his Companionship is not established, though he was born during the Prophet’s lifetime.” Ibn Ḥibbān included him among the trustworthy Successors in al-Thiqāt al-Tābiʿīn (3/265).
I say: It is astonishing that al-Ḥāfiẓ Ibn Ḥajar remained silent regarding this fact and did not explain it in al-Munkadir’s biographical entry in al-Iṣābah, after mentioning that al-Ṭabarānī and others had listed him among the Companions.
The second is that this al-Munkadir is unknown, for Ibn Abī Ḥātim mentioned no one who narrated from him other than his nephew, ʿAbd Allāh ibn Rabīʿah ibn ʿAbd Allāh ibn al-Hudayr. Ibn Ḥibbān said, “His son Muḥammad ibn al-Munkadir narrated from him,” and added nothing further. Thus, he is a Successor of unknown status. The hadith is therefore mursal, but it is acceptable as a corroborating report, since the remaining narrators are trustworthy, despite some weakness in Ḥurayth ibn al-Sāʾib. Ibn Maʿīn and Ibn Ḥibbān declared him trustworthy, while Aḥmad, Abū Ḥātim, and others said:
