The Sufficient (Vol 3) · Hadith 1655 (#Ḥadīth #4)

4ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ عُثْمَانَ بْنِ عِيسَى عَنْ سَمَاعَةَ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ الْسَّلام) عَنِ الصَّلاَةِ يَوْمَ الْجُمُعَةِ فَقَالَ أَمَّا مَعَ الإِمَامِ فَرَكْعَتَانِ وَأَمَّا مَنْ يُصَلِّي وَحْدَهُ فَهِيَ أَرْبَعُ رَكَعَاتٍ بِمَنْزِلَةِ الظُّهْرِ يَعْنِي إِذَا كَانَ إِمَامٌ يَخْطُبُ فَأَمَّا إِذَا لَمْ يَكُنْ إِمَامٌ يَخْطُبُ فَهِيَ أَرْبَعُ رَكَعَاتٍ وَإِنْ صَلَّوْا جَمَاعَةً.

4. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from ‘Uthman ibn ‘Isa from Sama‘ah who has said the following: “I once asked abu ‘Abd Allah , about Salah (prayer) on Friday. He (the Imam) said, ‘With Imam it is two Rak‘at but if one performs it alone, it is four Rak‘at like al-Dhuhr Salah (prayer). If there is an Imam he delivers a speech but if the Imam who delivers a speech is not there, then it is four Rak‘at even if performed in congregation.’”
