He it is Who sent among the unlettered ones a Messenger (Muhammad SAW) from among themselves, reciting to them His Verses, purifying them (from the filth of disbelief and polytheism), and teaching them the Book (this Quran, Islamic laws and Islamic jurisprudence) and Al-Hikmah (As-Sunnah: legal ways, orders, acts of worship, etc. of Prophet Muhammad SAW). And verily, they had been before in mainfest error;
The likeness of those who were entrusted with the (obligation of the) Taurat (Torah) (i.e. to obey its commandments and to practise its legal laws), but who subsequently failed in those (obligations), is as the likeness of a donkey who carries huge burdens of books (but understands nothing from them). How bad is the example (or the likeness) of people who deny the Ayat (proofs, evidences, verses, signs, revelations, etc.) of Allah. And Allah guides not the people who are Zalimun (polytheists, wrong-doers, disbelievers, etc.).
Ya ayyuha allatheena amanoo itha noodiya lilssalati min yawmi aljumuAAati faisAAaw ilathikri Allahi watharoo albayAAa thalikum khayrun lakum in kuntum taAAlamoona
The Noble Quran
O you who believe (Muslims)! When the call is proclaimed for the Salat (prayer) on the day of Friday (Jumu'ah prayer), come to the remembrance of Allah [Jumu'ah religious talk (Khutbah) and Salat (prayer)] and leave off business (and every other thing), that is better for you if you did but know!
Waitha raaw tijaratan aw lahwan infaddoo ilayha watarakooka qaiman qul ma AAinda Allahi khayrun mina allahwi wamina alttijarati waAllahu khayru alrraziqeena
The Noble Quran
And when they see some merchandise or some amusement [beating of Tambur (drum) etc.] they disperse headlong to it, and leave you (Muhammad SAW) standing [while delivering Jumu'ah's religious talk (Khutbah)]. Say "That which Allah has is better than any amusement or merchandise! And Allah is the Best of providers."
