Tafsir of An-Nahl 16:53

وما بكم من نعمة فمن الله

And whatever of blessings and good things you have, it is from Allah. Allah tells us that He is the One Who has the power to benefit and harm, and that the provisions, blessings, good health and help, His servants enjoy are from His bounty and graciousness towards them.

ثم إذا مسكم الضر فٳليه تجٲرون

Then, when harm touches you, to Him you cry aloud for help. meaning because you know that none has the power to remove that harm except for Him, so when you are harmed, you turn to ask Him for help and beg Him for aid. As Allah says:

وإذا مسكم الضر فى البحر ضل من تدعون إﻻ إياه فلما نجكم إلى البر أعرضتم وكان اﻻنسن كفورا

And when harm touches you at sea, those that you call upon vanish, except for Him. But when He brings you safe to land, you turn away. And man is ever ungrateful. (17:67) Here, Allah tells us:

ثم إذا كشف الضر عنكم إذا فريق منكم بربهم يشركون
