Sahih al-Bukhari
Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
"...But if he (the guardian) is poor, let him have for himself what is just and reasonable (according to his work). And when you release their property to them, take witness in their presence; and Allah is All-Sufficient in taking account." (V.4:6)
Narrated Aisha:
regarding the Statement of Allah: "And whoever amongst the guardian is rich, he should take no wages, but if he is poor, let him have for himself what is just and reasonable (according to his work). This Verse was revealed regarding the orphan's property. If the guardian is poor, he can take from the property of the orphan, what is just and reasonable according to his work and the time he spends on managing it.
