Hadith text
Narrated Hakim bin Hizam:The Prophet (ﷺ) said, "The buyer and the seller have the option to cancel or to confirm the deal, as long as they have not parted or till they part, and if they spoke the truth and told each other the defects of the things, then blessings would be in their deal, and if they hid something and told lies, the blessing of the deal would be lost
Hakim bin Hizam (رضی اللہ عنہ) bataate hain: Nabi ne farmaya: "Khareedne aur bechne wale ko saudebaazi radd karne ya poori karne ka ikhtiyaar hai jab tak woh alag na ho jaayen ya alag ho jaayen, aur agar unhone sach bola aur ek-doosre ko cheez ke aib bataye, to unki saudebaazi mein barkat hogi, aur agar unhone kuch chhupaya aur jhoot bola, to saudebaazi ki barkat khatam ho jaayegi."
