What is the explanation of the hadith, “Nothing can avert the divine decree except supplication”?

In the saying of the Messenger (peace and blessings be upon him): , and , how can the divine decree be averted?
And how does Allah delay [death] to increase lifespan, while Allah says: [Al-Munafiqun: 11]?
There is no contradiction between these two. Kindness to parents increases lifespan, and maintaining family ties, and . So supplication is among the causes of averting the conditional divine decree, and maintaining family ties and kindness to parents are among the causes of increasing the conditional lifespan. Indeed, the divine decree is of two types: a conditional decree and a finalized decree that is not conditional. As for the finalized decree, there is no way to change it, such as a fixed death or the like. As for the conditional decree: this is contingent upon its causes. Allah, the Exalted, may make the expansion of sustenance and the lengthening of lifespan contingent upon maintaining family ties and kindness to parents. Thus, his lifespan is increased by what He has decreed that he will be kind to his parents and maintain his family ties. And this decree is averted by supplication; he is destined to be afflicted with such and such, except if he supplicates with such and such. Allah may have decreed that he will supplicate, so this conditional decree is removed by the supplication. The conditional decree is that in which the expansion of sustenance is beneficial, in which kindness is beneficial, and in which supplication is beneficial. As for the finalized decree that is not conditional: this occurs at its time, and nothing can avert it [Al-Munafiqun: 11]. So when the time comes for the conditional and the non-conditional, it ends.
