“When any of you comes on a Friday while the imam is giving the sermon, let him pray two rakʿahs [briefly], shortening them [then let him sit].”

This ḥadith has reached us from a number of Companions, both in full and in abridged form. Among them are:

1. Jābir ibn ʿAbd Allāh al-Anṣārī. His narration is the most complete, and it is transmitted through several chains, the fullest and soundest of which is:
   1 – al-Aʿmash, from Abū Sufyān, from him.
   It is recorded by Muslim—whose wording has been cited here—and by Abū Dāwūd, Ibn Mājah, al-Ṭaḥāwī, and Aḥmad; the two bracketed additions belong to the last two.

   Al-Walīd Abū Bishr also followed Sufyān (whose name is Ṭalḥah al-Iskāf) with the same additional wording.
   This version is reported by Abū Dāwūd, Aḥmad, and al-Dāraquṭnī.

2. ʿAmr ibn Dīnār relates it from Jābir in an abridged form:
   “A man came while the Messenger of Allah ﷺ was on the pulpit on a Friday delivering the sermon. He said to him, ‘Have you prayed two rakʿahs?’ He replied, ‘No.’ He said, ‘Then pray.’”
   It is recorded by al-Bukhārī, Muslim, Abū Dāwūd, and al-Nasāʾī.
