Primary text
It is impermissible to conduct a Murabaha sale if the item was purchased from one's father, son, or any person whose testimony is not accepted unless the situation is clearly explained. This ruling is founded on the suspicion of favoritism in such relationships, which mandates transparency regarding the original cost basis.

Al-Shafi'i, Abu Yusuf, and Muhammad permit it without such clarification, analogizing it to a purchase from a stranger, as the contract itself was valid.
