Amongst the other things that Islam has encouraged and called for is adopting leniency in buying and selling. It was narrated on the authority of Jaabir ibn ‘Abdullaah, may Allaah be pleased with him, that the Messenger of Allaah, peace and blessing be upon him, said: “May Allaah’s mercy be on him who is lenient in his buying, selling, and in demanding back his money.” [Reported by Al-Bukhaari and others].
It was also reported from Huthayfah, may Allaah be pleased with him, that the Messenger of Allaah, peace and blessing be upon him, said:
“A servant from amongst the servants of Allaah was brought to Him whom Allaah had endowed with riches. He (Allaah The Almighty) said to him: “What (did you do) in the world?” He (the person) said: “They cannot conceal anything from Allaah.” He added: “O my Lord, You endowed me with Your riches. I used to enter into transactions with people. It was my nature to be lenient to (my debtors). I showed leniency to the solvent and gave respite to the insolvent, whereupon Allaah The Almighty said: “I have more right than you to do this to connive at My servant.” [Reported by Al-Bukhaari and Muslim].
Dear reader, there are many types of adopting leniency such as not to go extremely regarding price, especially if they buyer is known with poverty, little money, and also rescinding a sale with a Muslim who is not happy with his transaction for no one will do so except the regretful whom sale causes harm to.
One should not be a reason for causing harm to his fellow Muslim brother. Therefore, it was narrated in a Saheeh (authentic) Hadeeth on the authority of Abu Hurairah, may Allaah be pleased with him, that the Messenger of Allaah, peace and blessing be upon him, said: “Whoever rescinds a sale with a Muslim who is not happy with his transaction, Allaah Will Cancel his slip on the Day of Resurrection.” [Reported by Abu Daawood with a Saheeh Sanad (i.e. authentic chain of transmission)].
