✅Answer: Please pay attention to the following narrations:

1 عَنْ سَمَاعَةَ بْنِ مِهْرَانَ عَنْ أَبِي عَبْدِ اللَّهِ فِي الرَّجُلِ لَا يَغْتَسِلُ يَوْمَ الْجُمُعَةِ فِي أَوَّلِ النَّهَارِ قَالَ يَقْضِيهِ مِنْ آخِرِ النَّهَارِ فَإِنْ لَمْ يَجِدْ فَلْيَقْضِهِ يَوْمَ السَّبْتِ.

📚Al-Tahdhib, Vol. 1, p. 113

Translation: Imam Sadiq (peace be upon him) said about a person who does not perform ghusl at the beginning of Friday: He should make it up at the end of the day. If he cannot, he must make it up on Saturday.

2 عَنْ عَبْدِ اللَّهِ بْنِ بُكَيْرٍ عَنْ أَبِي عَبْدِ اللَّهِ قَالَ: سَأَلْتُهُ عَنْ رَجُلٍ فَاتَهُ الْغُسْلُ يَوْمَ الْجُمُعَةِ- قَالَ يَغْتَسِلُ مَا بَيْنَهُ وَ بَيْنَ اللَّيْلِ فَإِنْ فَاتَهُ اغْتَسَلَ يَوْمَ السَّبْتِ

📚Al-Tahdhib, Vol. 1, p. 113

Translation: Abdullah ibn Bukayr said: I asked Imam Sadiq (peace be upon him) about a person who misses ghusl on Friday; he said: He must perform ghusl from that time until the night. If he misses it again, he performs ghusl on Saturday.

3 عَنْ أَبِي جَعْفَرٍ قَالَ: لَا بُدَّ مِنَ الْغُسْلِ يَوْمَ الْجُمُعَةِ فِي السَّفَرِ وَ الْحَضَرِ وَ مَنْ نَسِيَ فَلْيُعِدْ مِنَ الْغَدِ.

📚Al-Kafi, Vol. 3, p. 43

Translation: Imam Baqir (peace be upon him) said: On Friday, whether in travel or at home, there is no escape from the Friday ghusl (one must perform ghusl). And whoever forgets, he must make it up the next day (i.e., on Saturday).

4 عَنْ زُرَارَةَ قَالَ: قَالَ أَبُو جَعْفَرٍ لَا تَدَعِ الْغُسْلَ يَوْمَ الْجُمُعَةِ فَإِنَّهُ سُنَّةٌ وَ شَمَّ الطِّيبِ وَ لُبْسَ صَالِحِ ثِيَابِكَ وَ لْيَكُنْ فَرَاغُكَ مِنَ الْغُسْلِ قَبْلَ الزَّوَالِ

📚Al-Kafi, Vol. 3, p. 417

Translation: Imam Baqir (peace be upon him) said: Do not neglect performing ghusl on Friday, for it is a tradition, and also do not neglect using perfume and wearing proper and good clothes, and your completion of ghusl should be before noon.

✅Based on the narrations, the Friday ghusl is one of the instructions of the Ahl al-Bayt (peace be upon them) on Friday, and the narrational evidence shows that it is performed from after the dawn until noon. And according to the above narrations, a person who misses ghusl during this time frame makes it up until the night. And if he misses it again, he makes it up on Saturday.

✅No instruction has been given to make up the Friday ghusl on the night of Saturday, and therefore, a person who does not make up the Friday ghusl from after noon on Friday until the time of the call to prayer for Maghrib makes it up on Saturday, not on the night of Saturday.

✅No instruction has been given in actionable narrations to make up the Friday ghusl after Saturday.
