Abu Siba’ says that once I bought a she-camel from the house of Sayyiduna Wathilah. When I was about to leave with the she-camel, I met Sayyiduna Wathilah. He was coming, pulling his cloak. He asked me,“O servant of Allah, have you bought it?”I said,“Yes.”He asked,“Did they tell you everything about it?”I said,“What do you mean by everything?”He said,“This one that appears healthy and strong—tell me, do you want to travel on it or slaughter it for meat?”I said,“I want to go for Hajj on it.”He said,“Then know that there is a hole in its hoof.”At this, the owner of the she-camel said,“May Allah have mercy on your condition! Do you want to ruin my deal?”He replied,“I heard the Prophet ( صلی اللہ علیہ وسلم ) say: ‘It is not permissible for a man to sell something without disclosing its defect, and it is not lawful for one who knows of the defect not to mention it.’”
