Is it permissible for the landlord to take the tenant's belongings, which were left in the premises—valued at 500 riyals—in exchange for a debt owed by the tenant amounting to 2000 riyals?

A Muslim's property is sacrosanct, except when taken by right. Among these rights is the issue of "al-Dhafar" (seizing one's right). This means that if someone has a right owed by a procrastinator, a thief, or an usurper, and the rightful owner gains possession of the exact item owed or of the usurper's property, then they are permitted to take it and reclaim their right from it. Therefore, there is no impediment to recovering the rent for the premises from the procrastinating tenant who denies the right. If you take his belongings, then evaluate them at their true price with the help of trustworthy experts.
