Allah is the Best Disposer of Affairs:

Allah is the Best Disposer of Affairs

In the event of fear and anxiety one should seek the help of Allah and frequently recite this ayah of the glorious Qur’an; “Allah (Alone) is Sufficient for us, and He is the Best Disposer of affairs (for us).” (3:173).

Ibn ‘Abbas (May Allah be pleased with them) said: When (Prophet) Ibraheem(عَلَيْهِ وَسَلَّم) was thrown into the fire, he said: “Allah (Alone) is sufficient for us, and, He is the Best Disposer of affairs.” So did Messenger of Allah, Muhammad (ﷺ), when he was told: “A great army of the pagans had gathered against him, so fear them”. But this (warning) only increased him and the Muslims in Faith and they said: “Allah (Alone) is sufficient for us, and He is the Best Disposer of affairs (for us)”. [Al-Bukhari].
