Prophet Muhammad’s advice on business: 1- He used to enjoin traders to be righteous and honest and to give charity. 2- He used to enjoin people to be tolerant and easy-going in buying and selling. 3- He used to give people their rights and urge others to do likewise. 4- He used to urge people to let a buyer cancel the transaction if he regrets it. 5- He used to bargain with people when buying, but he would not go so far as to undermine the real value of the item 6- He used to urge people to give a little more when weighing. 7- He used to enjoin people to give more time for a debtor who is in financial difficulty, or to waive the debt. 8- He forbade transactions involving Riba and transactions involving ambiguity.

Ahl Al-Bayt are the members of the household of the Prophet (peace and blessings be upon him). Allah has bestowed upon the Ahl Al-Bayt of the Prophet numerous virtues. There is no intercession specifically for the family of the Prophet (peace and blessings of Allah be upon him).

The sacred months are Dhu’l-Qa‘dah, Dhu’l-Hijjah, Muharram and Rajab. Some of the scholars have stated that the wisdom behind Rajab being separate from the other sacred months was to enable the Arabs to do ‘umrah in the middle of the year, and that the consecutive months for the purpose of Hajj.

The one who says that the age of Islam started with the Hijrah is referring to the calendar and the people agreed upon creating a system so that people could know the dates of events and define the times of contracts, the dates of visits by delegations, and the like. As for the beginning of Islam itself and people's awareness of it, we do not need to point out that this took place before that time.
