Ibn `Abbas (May Allah be pleased with them) said: When (Prophet) Ibrahim (Abraham) 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 (PBUH) 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)”.
Even in the worst of circumstances, one should always have faith & trust in Allah. Nothing will happen to us unless what Allah has decreed & whatever he decrees is the best for His servant.
And we ask Allah (swt) to grant us the utmost trust and reliance in Him, ameen.
