Is it permissible to combine two wages from the mosque administration and the Ministry of Endowments for delivering the Friday sermon, whether the mosque administration is aware or not, knowing that the total of the two wages is small and does not exceed $8.5 per sermon and the distance traveled is 10 kilometers?

If the mosque administration provided you with money because you were not receiving a salary from the Ministry, you must inform them when this situation changes. Not informing them might be considered cheating and deception, and the Prophet, peace and blessings be upon him, said: "Whoever deceives is not of me." If you inform them, your conscience is cleared, and your request to keep the allowance due to your need for it does not justify concealing the matter.
