Ibn Majah

The Messenger of Allah (ﷺ) forbade selling food bought by measure until two Sa' have been measured - the Sa' of the seller and the Sa' of the buyer."[1]

"We used to buy food from troops of riders (i.e., the caravans) without knowing the amount, but the Messenger of Allah (ﷺ) forbade us to sell it until it had been delivered to us."

"I used to sell dates in the marketplace, and I would say: 'This was such and such an amount (when I bought it).' I Would give the purchaser a specific amount of dates according to the way it had been measured for me, and take my profit. Then I began to have some doubts about that, so I asked the Messenger of Allah (ﷺ), and he said: "When you name the amount, measure it in front of the purchaser."'

"I heard the Messenger of Allah (ﷺ) say: 'Measure your food, may you be blessed therein."'

"Measure your food, may you be blessed therein."

the Messenger of Allah (ﷺ) went to the market of Nabit,[1] and looked at it, and said: "This is not a market for you." Then we went to another market and looked at it, and said: "This is not a market for you." Then he came back to this market and walked around in it then he said: "This is your market. It will always be your market and no duty will be levied on it." (Do,if)

"I heard the Messenger of Allah (ﷺ) saying: 'Whoever goes to the Morning prayer first thing in the morning, he goes out with the banner of faith but whoever goes out to the marketplace first thing in the morning, he goes out under the banner of Iblis (Satan).' "

"Whoever says, when he enters the marketplace: 'La ilaha illallah wahdahu la sharika lahu, lahul-mulk wa lahul-hamdu, yuhyi wa yumitu, wa Huwa hayyun la yamutu, bi yadihil-khairu kulluhu, wa Huwa ala kulli shay'in Qadir (None has the right to be worshiped but Allah alone, with no partner, to Him belongs all sovereignty and to Him is the praise, He gives life and gives death, and He is Ever-Living and does not die; in His Hand is all goodness and He is Able to do all things),' Allah will record for him one million good deeds, and will erase from him one million bad deeds, and will build for him a house in Paradise. "

"O Allah, bless my nation in their early mornings (i.e., what they do early in the morning)." (Hasan)He said: "When he sent out a raiding party or an army, he would send them at the beginning of the day." He said: (1) "Sakhr was a man engaged in trade, and he used to send his goods out at the beginning of the day, and his wealth grew and increased."

"O Allah, bless my nation early in the morning of Thursday.' "
