The ruling on purchasing an item suspected to be stolen

Question:
He says: Honorable Shaykh, may Allah grant you success, a man passed by me wanting to sell a used mobile phone at a very attractive low price, and I suspected that the man might be a thief of it, due to the presence of some indications against him, such as the absence of the charger and the phone box. Is it permissible for me to buy this?

Answer:
No, as long as you have signs that he does not own this phone, do not buy it from him. Yes. And Allah the Exalted knows best, and may Allah send prayers and peace upon our Prophet Muhammad and upon his family and his Companions.
