(11) باب الصِّدْقِ فِي الْبَيْعِ وَالْبَيَانِ
Hakim b. Hazim (Allah be pleased with him) reported Allah's Messenger (ﷺ) as saying:
Both parties in a business transaction have the right to annul it so long as they have not separated; and if they speak the truth and make everything clear they will be blessed in their transaction; but if they tell a lie and conceal anything the blessing on their transaction will be blotted out.
