Shaykh Yasir Qadhi divulges details about a number of beneficial policies that were new and impossible to implement in Mecca
Economic policy -
All business must be done in this book
No taxes
Spiritual development - concerning Ramadan, Zakat and of course, Salah.
Political and military development - concerning Jihad. Explicit details have been shared about the stages of Jihad too.
The Prophet ﷺ and the sahabah engaged in many expeditions which had some specific goals:
Show the strength of the Muslims as an independent, political, economical and strong force to the Quraysh.
To deprive the Quraysh of money which was their key strength.
Increase the size of the Islamic State
Next, we get acquainted with the two types of military expeditions - the Ghazwa and the Sareeah. Which were they and how many were they in number?
The first expedition where some fighting occurred was on the sareeah of Ubaydah ibn al-Harith and Sa'ad ibn Abi Waqqas was the first person to throw an arrow in the way of Allah. The first significant expedition without any bloodshed was the Ghazwa tul Ushayra. The Prophet ﷺ took around 200 sahabah to attack the annual caravan that went up to Syria. And it had most of the wealth from Mecca. The leader of Mecca was Abu Sufyan and so this was sort of a precedent to the Battle of Badr.
The other was the sareeah tul Nakhla in which some sahaba were sent to find out information outside of Mecca which is when they saw a caravan with booty and decided to capture it in the sacred month of Rajab, killing one person in the process. The Prophet ﷺ said "I didn't tell you to fight or kill anyone". And Allah revealed the verse in Surah Baqarah. What was this verse? Listen intently and be mesmerized in the judgement of Allah in this difficult time.
These expeditions lead to the battle of Badr which is one of the biggest miracles in Islam and Allah called it the 'day of Furqan' - A victory that was unprecedented.
