I searched about but didn't find my answer and even asked some clergymen but no result! I know in the other religions women wore hijab like Jews but as we know in Arabian peninsula most people were idolators and had no religion (one god). Was there any hijab for women before Islam?

I'd look to know more about the "hilful fazool" agreement that took place in Makkah when the Prophet was still young? Why did he prefer it over red camels? What was do great about a simple protection agreement for a business man?

I want to know the status and significance of Ramadan and _sawm_ before the time of Muhammad ﷺ. For example, in one _hadeeth_ (reported by Wathilah ibn al-Asq’a): >The Prophet (peace and blessings of Allah be upon him) has told us about the history of its revelation, as it was narrated from Wathilah ibn al-Asq’a that the Messenger of Allah (peace and blessings of Allaah be upon him) said: The Scriptures of Ibrahim (peace be upon him) were revealed on the first night of Ramadan, the Torah was revealed on the sixth of Ramadan, the Gospel was revealed on the 13th of Ramadan, and the Quran was revealed on the 24th of Ramadan[Ahmad 16370]. Similarly, is there any significance of Ramadan and fasting during the time of prior Prophets? At the time of _jahiliyyah_, did people still fast? I would appreciate secondary sources as references.

Based on this Question and as we know that all weekdays in Arabic are associated with a number: - Sunday =al-Ahad - 1 الأحد - Monday =al-Ithnayn - 2 الاثنين - Tuesday = a-Thulata' - 3 الثلاثاء - Wednesday = al-Arbi'a' - 4 الأربعاء - Thursday = al-Khamys - 5 الخميس - Friday = al-Jumu'a الجمعة - Saturday = a-Sabt - 6 السبت The names of both Friday and Saturday have been quoted in the Quran! So it it seems that these names have been known, at least to some people! My point is did the weekdays have other names before Islam, and if the Friday already was known as Jumu'a, what was the meaning or reason of such a nomenclature before Islam (in Jahiliya)?

I notice many references in the Qur'an, to "wealth and sons", in particular, God warning the pagans that their wealth and sons will not avail them in the end. What pagan belief about wealth and sons was God addressing with these warnings?

It was said in the Torah, that one may divorce his wife handing her a letter of Divorce, But what was the practice among the Arabs before and after Prophet Muhammad?
