“And if We were to send a wind and they saw it turn yellow, they would surely persist in disbelief thereafter. For you cannot make the dead hear, nor can you make the deaf hear the call when they turn away, retreating. Nor can you guide the blind away from their misguidance. You can make none hear except those who believe in Our signs and submit to Allah. Allah is the One who created you from weakness; then, after weakness, He gave you strength; then, after strength, He gave you weakness and gray hair. He creates whatever He wills, and He is the All-Knowing, the All-Powerful.” (51–54)
“So observe the trace of Allah’s mercy”: this is how the people of the Hijaz, Basra, and Abu Bakr recited it (1).

In other words, they rejoice when there is abundance; yet if I were to send a punishment upon their crops, they would deny My former blessing.
“For you cannot make the dead hear, nor can you make the deaf hear the call when they turn away, retreating. Nor can you guide the blind away from their misguidance. You can make none hear except those who believe in Our signs and submit to Allah.” (2)
“Allah is the One who created you from weakness”: the word “weakness” has been recited with either a u-vowel or an a-vowel on the letter dad. The u-vowel is the dialect of Quraysh, while the a-vowel is the dialect of Tamim. The meaning of “from weakness” is: from a sperm-drop; that is, from something characterized by weakness—from fluid characterized by weakness—as He says:
