In the book "العرف الناشر" (pdf), fiqh Al-maliki, it is mentioned in page 240, that there is ijma (consensus) among the scholars that the prayer in Jumua is accepted with just regular wudu (ablution).
I guess this is derived from the hadith:
مَنْ تَوَضَّأَ فَأَحْسَنَ الْوُضُوءَ ثُمَّ أَتَى الْجُمُعَةَ فَاسْتَمَعَ وَأَنْصَتَ غُفِرَ لَهُ مَا بَيْنَهُ وَبَيْنَ الْجُمُعَةِ وَزِيَادَةُ ثَلاَثَةِ أَيَّامٍ وَمَنْ مَسَّ الْحَصَى فَقَدْ لَغَا "
He who performed ablution well, then came to Friday prayer, listened (to the sermon), kept silence all (his sins) between that time and the next Friday would be forgiven with three days extra, and he who touched pebbles caused an interruption.
مَنْ أَتَى الْجُمُعَةَ فَتَوَضَّأَ فَبِهَا وَنِعْمَتْ ، وَمَنِ اغْتَسَلَ فَالْغُسْلُ أَفْضَلُ
Now the hadith I am asking about is this:
أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ غُسْلُ يَوْمِ الْجُمُعَةِ وَاجِبٌ عَلَى كُلِّ مُحْتَلِمٍ
Allah's Messenger (ﷺ) (p.b.u.h) said, "The taking of a bath on Friday is compulsory (wajib) for every male (Muslim) who has attained the age of puberty."
Question: What does "wajib" mean in this hadith about doing ghusl in Jumua (Friday)?
It is mentioned that doing ghusl is sunnah mo'akada, but not obligatory. So I basically wonder what wajib means in the hadith if it really isn't "wajib" as in our terminology. (i.e it is called sunnah mo'akada then it can't be called wajib or obligatory)
In this hadith Umar responds on a man who didn't do ghusl and indicates that it is obligatory by quoting the Prophet.
P.S: I've read Bin Baz (salafi scholar) answer about this, but I'd rather want to hear other opinions too, because his description wasn't very convincing... But if you use some of his arguments, then explaining them more, that is okay for me, but adding more scholarly opinions is preferable.
