“Al-Mughirah bin Shu’bah wrote to Mu’awiyah (Saying) that the Messenger of Allah (ﷺ) used to say following every prayer, after the taslim: ‘La Ilaha Illallah wahdahu la sharika lah, lahul-mulk wa lahul-hamd wa huwa ‘ala kulli shay’in qadir. Allahumma la mani’ lima a’taita wa la mu’tia lima mana’ta wa la yanfa’u dhal-jaddi minka al-jadd. (There is none worthy of worship except Allah (ﷺ) alone with no partner or associate. He is the Dominion and to Him be all praise, and He is able to do all things. O Allah, one can withhold what You have given and none can give what You have withheld, and no wealth or fortune can benefit anyone for from You comes all wealth and fortune.)’
“O people, you have invented kinds of transactions, I do not know what they are, but make sure it is gold for gold, of the same weight, or silver for silver, of the same weight. There is nothing wrong with selling silver for gold, hand to hand, giving more silver than gold, but no credit is allowed. When you sell wheat for wheat and barley for barley, it should be measure for measure, but there is nothing wrong with selling barley for wheat, hand to hand, giving more barley than wheat, but no credit is allowed. And when you sell dates for dates, it should be measure for measure” And he mentioned salt, “measure for measure, and whoever gives more or asks for more has engaged in Riba.
“The messenger of Allah said: ‘Gold for gold, of equal measure; silver for silver, of equal measure; salt for salt, dates for dates wheat for wheat, barley for barley, like for like. Whoever gives more or takes more has engaged in Riba.”‘ (Sahih) The wording is that of Muhammad Yaqub did not mention – “Wheat for wheat”.
“He said: If these classes differ, sell as you wish if payment is made on the spot.”
The Prophet (ﷺ) was brought a necklace in which there were gold and pearls. (The narrators AbuBakr and (Ahmad) Ibn Mani’ said: The pearls were set with gold in it, and a man bought it for nine or seven dinars.) The Prophet (ﷺ) said: (It must not be sold) till the contents are considered separately. The narrator said: He returned it till the contents were considered separately. The narrator Ibn Asa said: By this I intended trade. Abu Dawud said: The word hijarah (stone) was recorded in his note-book before, but he changed it and narrated tijarah (trade).
The Prophet (ﷺ) said: The similitude of the one who takes back what he gifted is like that of a dog which vomits and then it eats vomit. When a donor seeks to take back (his gift), it should be made known and he informed why he sought to take it back. Then whatever he donated should be returned to him.
I swear by Allah, I heard the Messenger of Allah (ﷺ) say: The happy man is he who avoids dissensions: happy is the man who avoids dissensions; happy is the man who avoids dissensions: but how fine is the man who is afflicted and shows endurance.
From his father, from his grandfather, that the Messenger of Allah (ﷺ) said: “Both the buyer and the seller retain the option as long as they did not separate, unless they agreed to making it optional. And it is not lawful for him to separate from his companion, fearing that he will change his mind.” This Hadith is Hasan and this means separating from him after the sale, fearing that he will change his mind. And if the separation referred to speech, and there was no option left for him after the sale, then this Hadith would be meaningless, since he (ﷺ) said: “And it is not lawful for him to separate from his companion, fearing that he will change his mind.”
