Is the tenant obligated to pay for the repair costs of an internal refrigerator malfunction that they did not intentionally cause, especially if the malfunction is old or resulted from a general electrical fault?

The tenant is entrusted with the leased property and is not liable for it unless he commits an act of transgression or negligence, as stated by Ibn Qudamah in Al-Mughni: "The leased property is a trust in the hands of the tenant; if it is damaged without negligence, he is not liable for it."

If the damage occurs due to authorized use, there is no liability, as stated in Fath al-Mu'in.

In case of dispute regarding transgression or negligence, recourse should be made to experts and specialists, as mentioned by Ibn Qudamah.
